The hull of the ZT 2 was largely identical to that of the "ZT 1". Apart from the 25 mm gun, having a stock of fifty rounds, the turret was fitted with a 7.5 mm machine gun, with 2250 rounds. The turret had both a large roof hatch and a smaller hatch in the back right facet. It had been intended to equip at least one ZT 2, in a ZT 2/ZT 3 platoon of four, with a radio set, but it is uncertain whether any was so modified.
