The Ulster Defence Regiment Cap Badge — History, Design and Collecting Guide

Introduction

The gold crowned harp was the cap badge worn by The Ulster Defence Regiment during twenty-two years of service in Northern Ireland. From 1970 until 1992, locally recruited UDR soldiers served alongside the Regular Army during the Troubles, carrying out patrols, guarding key installations, manning checkpoints and performing other security duties.

The badge is centred on a Maid of Erin-style Irish harp surmounted by the Queen's Crown in the St Edward's Crown pattern. It carries neither a regimental title nor a motto scroll. Its immediate ancestry can be traced to the crowned harp of The Royal Ulster Rifles.

When the UDR amalgamated with The Royal Irish Rangers on 1 July 1992, the design remained in use. Soldiers of the newly formed Royal Irish Regiment initially continued to wear the gold UDR-derived badge before the later adoption of the silver crowned-harp badge associated with the caubeen.

About This Guide

This guide covers the formation and service of The Ulster Defence Regiment, the development of its cap badge, its battalions, Greenfinches, Colours, medals and gallantry, amalgamation into The Royal Irish Regiment, and the identification of surviving UDR insignia.

The account is based principally on contemporary Parliamentary records, the National Army Museum, The Royal Irish Regiment's Virtual Military Gallery, official sealed-pattern records and published regimental history. Period UDR dress is distinguished from the post-1992 dress regulations of The Royal Irish Regiment.

Formation of The Ulster Defence Regiment

The Security Reforms of 1969

The UDR emerged from the serious unrest that affected Northern Ireland during 1969. The Royal Ulster Constabulary and Ulster Special Constabulary were under increasing pressure, while policing and internal security arrangements were subjected to major review.

The Hunt Committee recommended that the RUC should be relieved of military duties and that the Ulster Special Constabulary should be replaced. One of the proposed replacements was a locally recruited military force that could assist the Regular Armed Forces.

The Government announced the proposed Ulster Defence Regiment in Parliament on 12 November 1969. Its intended role was to meet what the Hunt Committee had described as armed guerrilla-type attacks. Duties included guarding key points and installations, patrolling, establishing checkpoints and roadblocks, and supporting the wider military security operation.

The new Regiment was to be an integral part of the British Army, controlled by the Secretary of State for Defence and commanded through the General Officer Commanding Northern Ireland. It was not a police organisation.

The Ulster Defence Regiment Act 1969

The Regiment had an unusual statutory foundation. The Ulster Defence Regiment Act 1969 received Royal Assent on 18 December 1969.

Members of the Regiment were members of the Armed Forces of the Crown. Their liability for service was, however, restricted to Northern Ireland, reflecting the locally recruited role for which the UDR had been created. Personnel could volunteer for training outside Northern Ireland, but they could not be compelled to do so.

This statutory basis later became significant when amalgamation was proposed. Primary legislation was required before the UDR could cease to exist and its members could transfer into The Royal Irish Regiment.

Recruiting and the Start of Operations

Recruiting began on 1 January 1970. The timetable was short because the new Regiment was intended to take over military security duties as the Ulster Special Constabulary was progressively stood down.

On 4 March 1970, Parliament was told that the UDR would undertake operational duties from 1 April 1970.

The first Commander of The Ulster Defence Regiment was Brigadier Logan Scott-Bowden, a Royal Engineer officer whose career included service during the Second World War and Korean War. He oversaw the Regiment's establishment, initial recruitment and training.

General Sir John D'Arcy Anderson was appointed the Regiment's first Colonel Commandant, a separate regimental appointment from Scott-Bowden's operational command.

Recruitment and Community Representation

Recruitment initially attracted applicants from both Protestant and Roman Catholic communities. The National Army Museum records that more than 4,700 men had applied by March 1970, although only around 1,600 of the initial applicants were accepted.

The Regiment was consequently below its intended strength when operations began. Recruitment increased subsequently, but maintaining the broad religious balance envisaged at formation became increasingly difficult.

Republican threats and attacks against UDR personnel, hostility encountered by some Catholic recruits, political developments and the worsening security situation all affected recruitment and retention. The National Army Museum records that Roman Catholics eventually averaged around three per cent of the Regiment's strength.

The resulting predominantly Protestant composition became an important part of the political debate surrounding the UDR and contributed to mistrust of the Regiment within sections of the nationalist community.

Key Dates

The Ulster Defence Regiment Cap Badge — How the Design Developed

The Royal Ulster Rifles Connection

The direct ancestor of the UDR cap badge was the badge of The Royal Ulster Rifles.

Familiar later Royal Ulster Rifles badges used a crowned Irish harp above a scroll carrying the Latin motto Quis Separabit — “Who Shall Separate Us?”

The Royal Irish Regiment's Virtual Military Gallery records a regimental story that an officer seeking a badge for the new UDR allegedly took a Royal Ulster Rifles cap badge and removed the lower motto scroll.

The museum presents the story cautiously, but the design relationship itself is clear: the UDR used the crowned Maid of Erin harp without the Royal Ulster Rifles' Quis Separabit scroll.

The 1970 Pattern

The resulting UDR badge was a gold-coloured crowned harp. The National Army Museum describes the device as a Maid of Erin-style harp surmounted by a St Edward Crown and identifies its design connection with The Royal Ulster Rifles.

The National Army Museum's sealed-pattern collection contains an other-ranks UDR cap badge dated 1970, accession number 1994-08-129. For collectors, the sealed pattern provides a firm period reference for comparison.

The badge itself contains neither the words ULSTER DEFENCE REGIMENT nor a separate motto scroll.

From UDR to The Royal Irish Regiment

The crowned harp remained in use when The Royal Irish Regiment was formed in 1992.

Soldiers initially continued to wear the gold-coloured UDR-derived badge in the green beret, while officers wore an embroidered silk-and-wire version on green backing cloth.

A silver-coloured crowned-harp badge was subsequently introduced for all ranks for wear in the caubeen. The Royal Irish Regiment museum records a further refinement in 2007, when the badge received sharper definition and green enamel separating the harp strings.

The Ulster Defence Regiment Cap Badge — Design and Meaning

The Maid of Erin Harp

The central device is an Irish harp in the Maid of Erin tradition, in which a female figure forms the forepillar of the instrument.

The harp is a long-established symbol of Ireland and had appeared on Irish military insignia long before the UDR was formed.

The Queen's Crown

The harp is surmounted by the St Edward's Crown, commonly described by collectors as the Queen's Crown when referring to insignia of the reign of Queen Elizabeth II.

The UDR existed from 1970 until 1992, making this the crown form associated with the Regiment's standard cap badge throughout its existence.

The Gold Finish

The Royal Irish Regiment museum records that the Royal Ulster Rifles-derived design was recoloured gold for the UDR. Gold-coloured metal consequently became a characteristic feature of UDR cap-badge insignia.

The Regiment's Role During the Troubles

A Locally Recruited Army Regiment

The UDR recruited locally and its statutory liability for service was restricted to Northern Ireland. This distinguished it from Regular Army units that could be deployed elsewhere and normally served in Northern Ireland for defined tours.

Its duties included:

• guarding key points and installations;
• patrolling;
• surveillance;
• vehicle checkpoints and roadblocks;
• supporting the wider Army security operation.

The locally recruited Regiment was not employed for crowd-control or riot duties.

Part-Time Service

The UDR was established principally as a part-time force. Many soldiers combined military duties with civilian jobs and family life.

Local recruitment provided detailed knowledge of roads, terrain and communities, but it also created a particular vulnerability. Soldiers' identities, homes and workplaces could be known locally, leaving personnel and their families exposed away from barracks as well as while on duty.

The Full-Time Element

The UDR had a full-time element before 1976. Parliament recorded 1,469 full-time members in June 1975.

From late 1976, the Government expanded the full-time element and increased its operational role, including the development of full-time operational platoons. It continued to grow and eventually accounted for a substantial proportion of the Regiment, while part-time soldiers remained fundamental to its organisation.

Expanding Operational Responsibility

At the same time, the UDR assumed wider territorial responsibilities. A Province Reserve was established in December 1975, followed on 24 May 1976 by the first UDR tactical areas of responsibility (TAORs), assigned to 9 UDR and 11 UDR.

By October 1988, Parliament stated that the Regiment provided the primary military support to the RUC in more than 80 per cent of Northern Ireland, with almost half of its soldiers serving full time. Parliament also described the UDR as having been continually on operations since its formation, a unique record for a British Army regiment.

The UDR Battalions

The UDR began with seven battalions. Four more followed between December 1971 and July 1972, bringing the Regiment to eleven. Later reductions and amalgamations reshaped the structure: 1/9 UDR formed on 20 May 1984, 7 UDR and 10 UDR amalgamated on 14 October 1984, 2/11 UDR formed on 30 September 1991 and 4/6 UDR on 25 November 1991.

The Greenfinches

The original 1969 legislation provided for the enlistment of men. The Ulster Defence Regiment Act 1973 changed the law to permit women to volunteer for service in the Regiment.

Women serving in the UDR became known as Greenfinches. The immediate operational requirement was for women searchers at checkpoints, where female suspects could not properly be searched by male soldiers. Greenfinches also served in clerical, radio and telephone duties. They were unarmed, but were integrated members of the Regiment rather than members of a separate women's organisation.

The first recorded operational deployment took place on the night of 28 October 1973, when four Greenfinches of C Company, 10 UDR, took part in a mobile patrol. Regular operational employment followed from 5 November.

Dress arrangements also changed with experience. Royal Irish regimental records note that Greenfinches were initially required to wear skirts rather than combat trousers on duty. This proved impractical for some tasks and weather conditions, and commanding officers were subsequently given discretion over the appropriate uniform.

Women continued to serve throughout the remainder of the UDR's existence and became an established part of the Regiment. Private Eva Martin of 6 UDR became the first Greenfinch to be killed when she died in an IRA attack on 2 May 1974. The current UDR Association Roll of Honour records four Greenfinches among the serving personnel killed during the Regiment's existence.

Patrols, Vehicles and the Shorland Armoured Car

UDR operating methods changed as the security threat developed. Soldiers patrolled on foot and in military vehicles, often in rural and border areas where ambushes, small-arms attacks and improvised explosive devices posed persistent dangers.

One vehicle particularly associated with the Regiment was the Shorland armoured car, developed in Northern Ireland around a long-wheelbase Land Rover chassis.

Shorlands provided protection against small-arms fire and fragmentation and were used extensively in rural operations. Regimental records include examples of the vehicles surviving serious attacks during the 1970s.

As the explosive threat increased, operating methods changed and greater use was made of foot patrols and other methods of moving soldiers through vulnerable areas.

The Colours of The Ulster Defence Regiment

The First Presentation — 29 June 1991

Queen Elizabeth II personally presented the first UDR Colours at Thiepval Barracks, Lisburn, on 29 June 1991.

Four battalions received Colours:

• 1st/9th Battalion The Ulster Defence Regiment;
• 3rd Battalion The Ulster Defence Regiment;
• 4th Battalion The Ulster Defence Regiment;
• 5th Battalion The Ulster Defence Regiment.

The Royal Irish Regiment's archive notes that The Queen would normally have presented Colours personally to regiments of which she was Colonel-in-Chief. Her decision to make the presentation to the UDR therefore gave the occasion particular significance.

Further Presentations

6 UDR received new Colours on 24 November 1991. A further ceremony took place on 4 April 1992, when the Duke of York presented Colours to additional UDR battalions.

The UDR therefore received its Colours only during the final year of its separate regimental existence.

Service, Casualties and Remembrance

Local service meant that danger did not necessarily end when a soldier completed a patrol. UDR personnel could be identified and targeted near their homes, civilian workplaces or while travelling off duty.

The current Ulster Defence Regiment Association Roll of Honour records 198 serving UDR soldiers killed as a result of terrorist action during the lifetime of the Regiment, with a further 62 former members killed after leaving. Earlier National Army Museum material gives totals of 197 serving members and 61 former members, while John Potter's regimental history records 197 UDR members killed by terrorists. Published totals are therefore not entirely consistent.

Parliamentary figures illustrate the extent of the off-duty threat. By March 1984, 141 UDR members had been killed; 117 of those deaths had occurred while the soldiers were off duty.

Those who died continue to be commemorated through veterans' organisations, regimental memorials and the wider Royal Irish regimental family.

Controversy and the Historical Record

The National Army Museum records that Loyalist paramilitary organisations attempted to infiltrate the Regiment and that some serving members became involved in sectarian crime. Other soldiers were expelled for paramilitary membership or for improperly supplying weapons.

These cases, together with the increasingly Protestant composition of the UDR, contributed to sustained mistrust of the Regiment among many nationalists.

The same National Army Museum account states that the vast majority of UDR soldiers served honourably and upheld the law.

Medals and Service Recognition

The Ulster Defence Regiment Medal

On 20 July 1982, the Government announced that Queen Elizabeth II had approved two new awards recognising long and efficient service in The Ulster Defence Regiment.

The Ulster Defence Regiment Medal could be awarded to part-time officers and members of the Regiment after 12 years of efficient service.

Its qualifying principle was comparable with the efficiency awards available within the Territorial Army.

Medal for Long Service and Good Conduct — Ulster Defence Regiment

The Medal for Long Service and Good Conduct — Ulster Defence Regiment was intended for soldiers of the permanent cadre after 15 years of service, on a basis comparable with the Regular Army Long Service and Good Conduct Medal.

General Service Medal

The introduction of the two UDR-specific medals did not replace operational campaign recognition. Members of the Regiment remained eligible for the General Service Medal with the clasp “Northern Ireland” under the qualifying rules then in force.

Gallantry and the Conspicuous Gallantry Cross

Individual Recognition

UDR personnel received numerous awards and commendations for gallant and meritorious service. By 20 October 1988, Parliament recorded that 43 awards for gallant and meritorious service had been made to UDR personnel during that year, including 19 Mentions in Despatches.

Collective recognition followed in 2006, fourteen years after the UDR had ceased to exist as a separate formation.

The Conspicuous Gallantry Cross — 6 October 2006

On 6 October 2006, Queen Elizabeth II presented the Conspicuous Gallantry Cross to The Royal Irish Regiment at the Balmoral Showgrounds in Belfast.

The award recognised the bravery, sacrifice and service of the Home Service battalions of The Royal Irish Regiment and their forebears, The Ulster Defence Regiment.

Corporal Clare Withers received the decoration from The Queen on behalf of the Regiment. Her father had been the last member of the Regiment to be killed by terrorists.

The presentation formed part of the Queen's Review and Final Parade of the Home Service battalions. The CGC was subsequently incorporated into Royal Irish regimental Colours.

Why UDR CGC Is Used

The formal 2006 award was made to The Royal Irish Regiment, not to the UDR as a separately existing regiment, because The Ulster Defence Regiment had ceased to exist fourteen years earlier.

The award nevertheless specifically recognised the UDR as the forebear of the Royal Irish Home Service battalions. This is the basis for the continuing use of descriptions such as UDR CGC within veterans' and commemorative settings.

Amalgamation into The Royal Irish Regiment

As part of the post-Cold War Army restructuring associated with Options for Change, the Government decided to merge The Ulster Defence Regiment with The Royal Irish Rangers.

Because the Regiment had been established by statute, Parliament had to legislate before its members could transfer into another regiment. The legislation provided for the UDR to cease to exist at the end of June 1992.

On 1 July 1992, The Ulster Defence Regiment amalgamated with The Royal Irish Rangers to form:

The Royal Irish Regiment (27th (Inniskilling), 83rd, 87th and The Ulster Defence Regiment).

The new Regiment initially comprised two Regular battalions and two Territorial battalions derived from The Royal Irish Rangers, together with seven Home Service battalions formed from the UDR. The Rangers provided the worldwide-deployable element, while the former UDR battalions continued the locally based Home Service role.

The Home Service establishment was gradually reduced as the security situation changed. The remaining Home Service battalions completed their disbandment by 31 July 2007, the date on which Operation BANNER formally ended.

A small residual number of Home Service personnel remained temporarily to complete the administrative rundown. That final residual element came to an end on 31 March 2008.

The UDR Legacy

The UDR remains part of the formal history of The Royal Irish Regiment, while the Ulster Defence Regiment Association continues traditions of comradeship, welfare and remembrance among former members.

Royal Irish museums, the National Army Museum and other collections preserve uniforms, badges, sealed patterns, photographs, documents and personal material relating to the Regiment.

Public commemoration includes the Ulster Defence Regiment memorial stained-glass window at Belfast City Hall, together with regimental and veterans' memorials elsewhere.

Dress, Headdress and Regimental Identity

The Green Beret

The green beret became closely associated with the UDR and provided the familiar background for its gold crowned-harp cap badge.

The beret continued to be used for a period after amalgamation. Royal Irish regimental history records that the newly formed Regiment initially wore the caubeen with service dress for formal duties while retaining the former UDR green beret for working dress.

The beret was later removed from Royal Irish dress regulations, leaving the caubeen as the normal Royal Irish regimental headdress in barracks.

Surviving Period Dress Evidence

Imperial War Museums preserves a female UDR No.2 Dress jacket manufactured in 1976. Its catalogue lists a WRAC Lovat Green skirt and a women's white shirt as associated items. The National Army Museum also records a 1975 sealed-pattern skirt associated with The Ulster Defence Regiment.

The Royal Irish Regiment's museum collection also preserves the khaki Service Dress, belt and green beret of a Warrant Officer of 2 UDR. These surviving uniforms provide valuable evidence of UDR-period dress when considered alongside contemporary photographs, regulations and sealed-pattern insignia.

Queen's Regulations and the Regulations of The Ulster Defence Regiment

UDR personnel were members of the Armed Forces and were subject to military discipline and Queen's Regulations.

The Regiment's unusual local role and terms of service required additional provisions. Contemporary Parliamentary records refer specifically to the published Regulations of the Ulster Defence Regiment, which supplemented the wider regulations governing the Army.

Historical UDR dress and service practice should therefore be assessed using contemporary UDR regulations, sealed patterns, photographs and regimental records rather than by applying later Royal Irish dress rules retrospectively.

Modern Army Dress Regulations

Modern Army Dress Regulations (All Ranks) relate to the present Army. Royal Irish regimental material identifies the caubeen as the authorised headdress of The Royal Irish Regiment under Part 9 of those regulations.

These regulations are relevant to Royal Irish dress after amalgamation, but they are not evidence that the same dress rules applied to The Ulster Defence Regiment between 1970 and 1992.

Official Sealed Patterns

Surviving National Army Museum holdings include UDR collar badges, buttons, rank badges, a pipers' brooch, a waistbelt clasp and official cap-badge material. These sealed patterns provide contemporary evidence for period insignia and manufacture.

Identifying and Collecting the Ulster Defence Regiment Cap Badge

Identifying the Standard Badge

The standard UDR cap badge can be recognised by the combination of:

• a Maid of Erin-style Irish harp;
• a St Edward's / Queen's Crown above the harp;
• a characteristic gold-coloured finish;
• no lower Quis Separabit scroll;
• no UDR title scroll.

The Royal Irish Regiment's own shop describes its UDR cap badge as a 1970–1992 gold metal badge with shank fitting, approximately 4.5 cm high.

Sealed-Pattern Evidence

The National Army Museum records an official 1970 sealed-pattern other-ranks UDR cap badge under accession number 1994-08-129.

NAM also holds a 1970 other-ranks UDR collar badge, accession 2003-10-12-8, whose catalogue description confirms the same Maid of Erin harp, St Edward Crown and Royal Ulster Rifles design connection.

Sealed patterns give collectors an official reference point and are generally more useful for establishing period characteristics than later commercial reproductions or unsupported collector convention.

Royal Ulster Rifles or UDR?

The similarity is deliberate: the UDR badge was derived from the Royal Ulster Rifles design.

• Royal Ulster Rifles: familiar later badges combine the crowned harp with the lower Quis Separabit scroll.
• Ulster Defence Regiment: the crowned harp appears without that motto scroll and in the characteristic UDR gold finish.

Royal Ulster Rifles insignia existed in different periods and forms, so identification should be based on the whole badge rather than a single feature.

UDR or Early Royal Irish Regiment?

The post-1992 continuation of the gold badge can complicate dating.

Soldiers of The Royal Irish Regiment initially wore the gold UDR-derived badge in the beret, while officers used an embroidered silk-and-wire form on green backing cloth. The later silver badge was introduced for all ranks in the caubeen.

Provenance, associated uniform, fittings, backing, finish and the date at which an item was obtained can therefore help distinguish late UDR insignia from early Royal Irish use.

Harp String Count

The Precision Military Emblems UDR badge featured with this guide has twelve visible harp strings.

That number should not be linked to battalion strength. The UDR began with seven battalions and later reached eleven, while the harp design itself predates the Regiment.

Fittings, Manufacture and Provenance

Period badges can vary in construction and fittings, so no single reverse feature or maker's mark should be treated as proof of authenticity. Comparison with sealed patterns, documented period examples and reliable provenance provides a stronger basis for identification.

A badge accompanied by a named uniform, service papers, photographs or other traceable material can usually be assessed more confidently than an isolated example without provenance.

Modern Licensed Display Pieces

Modern reproductions and display pieces should be distinguished clearly from original military-issued insignia.

Precision Military Emblems produces modern officially licensed heritage displays from authorised artwork. They are not represented as original military-issued UDR cap badges.
