I've finished the model and added some quirks and features. This is the standard G-93, with a driver/commander and a HMG in the second seat.
This is the G-93a Ozmot, with a superfiring MG position (not the most comfortable arrangement for the driver), and a third crew member is added to man the 3pdr anti-tank gun.
There is a hardtop version, the G-93b Korkodil, which is designated as a tank hunter, lacking secondary armament.
And lastly, the G-93c Astaba, where the commander is standing in the turret, manning the 3pdr gun that has a larger field of fire, the driver takes the front position, and a HMG can also fit.
