Source-derived summary

85 (Ulster) Signal Squadron was a military communications unit of the British Territorial Army, which formed part of the Royal Corps of Signals. The squadron was one of four signal squadrons which formed part of 40th (Ulster) Signal Regiment until its disbandment in 2009.

Formation

On 1 April 1947, 107th (Ulster) Independent Infantry Brigade was formed as the first Territorial Army (TA) brigade in Northern Ireland. The new brigade oversaw all TA troops in Northern Ireland (except those of Anti-Aircraft Command and coastal defence/regular units). 107th (Ulster) Independent Infantry Brigade Signal Squadron was formed shortly after to provide communications support to the brigade and its subordinate units.

In 1959 the Royal Corps of Signals went through an internal reorganisation, in which the numbering system in-place was completely revamped. This would bring the corps in-line with the Royal Artillery and Royal Engineers, which this reform was mostly based on. Troops of the TA within the corps were also reorganised along these same lines, in which all TA signal units below the level of divisional signal regiments became numbered in the 300 series. As part of this change, the squadron was retitled as 302 Signal Squadron. In 1961 when the TA was reduced and reorganised, the squadron added a prefix for their role, becoming 302 Signal Squadron (Infantry Brigade Group), though its role remained the same through these changes.

Editorial summary

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—2009, 1947, 1959, 1961—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Ulster, Signal and Squadron is the immediate research focus.
Editorial analysis

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.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 24, 2023. The linked authority identifier is Q106936095. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2009, 1947, 1959 and 1961.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. 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.

How to read it
