Well the churchill will be a nice addition. 6 saw the Battle at El Alamein. So we could use the Crusaders, Churchills (in limited numbers), Panzer IVs, Panzer IIIs, M3 Lee (got it right this time), and the M4 Sherman during its debut battle. Didn't early Panzers have an issue where they couldn't turn the turret so they had to expose their broadside to the enemy to shoot a guy on their flanks?
I'd probably use a Crusader in the MA as a tank.
