I’d like to suggest another possible unit for the British OOB: the
Tetrarch ICS. Like the other Tetrarchs it was an airborne light tank. Unlike the others its main armament was a 3 in. infantry support howitzer rather than a 2 pdr.
Tetrarch ICS.
The Tetrarch in Bovington Tank Museum is a Tetrarch ICS. There are some photos of it here:

Like the other Tetrarchs the ICS variant had smoke dischargers and a commander’s Bren gun – which was stowed on the turret. I’m not sure whether the Bren should be added as a weapon in the game though. It was used by the commander who in combat acted as a loader for the main armament. He would not have been able to use both weapons at the same time.
I do not know how many rounds of 3 inch ammunition the Tetrarch ICS could carry. It would have been less than the 50 rounds carried by other Tetrarchs. Note: the Tetrarchs (including the Light Tank Mk VII) in the game only have 40 rounds for their main armament.
A new Tetrarch ICS unit would not need a new pic/LBM. The LBM already being used for Tetrarchs is probably a pic of a Tetrarch ICS in any case.
