22nd Armoured Brigade is theoretically a good choice to model amongst the armoured brigades which participated in Operation CRUSADER, since they were present at the start of the operation in the (in)famous first battle of Bir el Gobi, at Sidi Rezegh, with the remainder of the brigade part of a composite regiment under 4th Armoured Brigade around Tobruk (see this link), and then in the pursuit, and the final tank battle of the operation in the Uadi al Faregh near el Agheila, on 27/28 December 1941 (see this older entry with a German report about that battle).

They did switch tanks in one of the regiments, from Crusaders to M3 ‘Honey’ light cruisers, so the modeller has that much more to paint.
