Notes
a. Filled out by mobilisable personnel that had fulfilled their active-duty period in Staff and Staff Company, 12 Armoured Infantry Brigade up to six and a half years prior to mobilisation.1
b. RIM battalion, filled by mobilisable companies and platoons that had fulfilled their active-duty period in 17 Armoured Infantry Battalion between four and twenty months prior to mobilisation.1 4
c. RIM battalion, filled by mobilisable companies and platoons that had fulfilled their active-duty period in 47 Armoured Infantry Battalion between four and twenty months prior to mobilisation.1 4
d. RIM company, filled by mobilisable platoons that had fulfilled their active-duty period in 12 Armoured Antitank Company between four and twenty months prior to mobilisation.1 4
e 58 Tank Battalion (RIM) was to transition from Centurion Mk 5/2 to Leopard 1V as a whole in October 1987, concurrently adopting a new organisation type which would add a fourth tank squadron to the battalion's war strength (the old battalion organisation is described in detail here). This is per the planning of July 1985; given the persistence of the problems with the Leopard 1 upgrading programme and the delays these had already caused it is quite possible that further delays occurred. The last Leopard 1V was delivered on 16 December 1987, however.2 A, B and C Squadron were each filled by a mobilisable squadron that had fulfilled their active-duty period in 59 Tank Battalion between four and twenty months prior to mobilisation. D Squadron, not falling under the RIM system, would be filled by the personnel of A Squadron for ten months after their 14 to 16-month RIM period in that unit had expired.3 4
f. RIM company, filled by mobilisable platoons that had fulfilled their active-duty period in 12 Armoured Engineer Company between four and twenty months prior to mobilisation.1 4
g. RIM battalion, filled by mobilisable batteries that had fulfilled their active-duty period in 11 Horse Artillery Battalion between four and twenty months prior to mobilisation.1 4
h. GRIM company, largely filled by mobilisable platoons that had fulfilled their active-duty period in 13 Brigade Supply Company between four and twenty months prior to mobilisation.1 4
i. GRIM company, largely filled by mobilisable platoons that had fulfilled their active-duty period in 12 Brigade Repair Company between four and twenty months prior to mobilisation.1 4
j. RIM company, filled by mobilisable platoons that had fulfilled their active-duty period in 12 Brigade Medical Company between four and twenty months prior to mobilisation.1 4

Combat Formations
Following the Royal Army's tactical doctrine and established modus operandi the brigade would not fight in the organic order of battle displayed above but form combined-arms battle groups, as illustrated in Unit Organisation and Equipment, Mixed Battalions and Company Teams.
