I’d like to make a small suggestion regarding British airborne tanks: add smoke dischargers.
The units involved are spob07, Units 066 (Tetrarch), 734 (Tetrarch with Little John adaptor) and 297 (M22 Locust).
Armour in Profile Number 11: Light Tank Tetrarch says that Tetrarchs were fitted with smoke dischargers when they were used operationally - one on each side of the turret. Each tank was issued with eight smoke bombs to use with them.

I believe that British airborne Locusts were equipped in the same way. A photo of such a Locust with smoke dischargers.
