107th (Ulster) Brigade
military unit
The 107th Brigade, later 107th (Ulster) Brigade was an infantry formation of the British Army which saw service in the First World War. The brigade was later reformed during the Cold War and finally disbanded in 2006, following the drawdown of Operation Banner.
History
World War I
The Brigade traces its historic title back to the First World War when the original 107th Infantry Brigade fought with distinction, alongside its sister formations of 108th Infantry Brigade and 109th Infantry Brigade, as the senior component of 36th (Ulster) Division. In September 1914 it was raised the 1st Brigade of that Division, but on 2 November 1914 it was renumbered 107. The 36th Division itself had been formed in September 1914 as part of the New Armies raised by Kitchener. It consisted of the old Ulster Volunteer Force, which had originally been raised to resist the imposition of Home Rule.
Casualties throughout the War meant that many of the original battalions were to be amalgamated or disbanded as hostilities continued. In early 1918, on re-organisation, 107 Brigade consisted of the 1st and 2nd (Regular) and the 15th (Service) Battalions of the Royal Irish Rifles. In March 1918 the 36th Division, in the St Quentin Sector, was part of the Fifth Army and it was upon this Army that the main weight of the German spring offensive fell. The retreat which followed ended on 29 March and the Ulster Division moved north to the Ypres Salient.

Why this record matters
The phrase “military unit” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jun 15, 2026. The linked authority identifier is Q4546721. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2006, 1914 and 1918.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
