History

The OT-62 series of vehicles is Czechoslovak take on amphibious armored personal carrier that could serve multi-purpose roles, such as mine layers, radio stations and tank destroyers. The first prototype of this vehicle mounted a small turret prototype, which mounted modified early stage of Tarasnice 21 (T21), the same vehicle would later also be modified to mount 82mm BzK vz.59A for trials, where the roof of the fighting comparment was removed to fit more munition inside. During the development the small turret was also removed off of the vehicle for wider gun traverse of the recoiless rifle. It’d be later installed back.

The OT-62A is production variant of the first prototype, mounting the small turret with UK vz.59 machine gun and Tarasnice 21 (T21) recoiless rifle, in later stages of production the Tarasnice 21 (T21) recoiless rifle was removed, with modification into OT-62D the machine gun was also removed, though early stage of this vehicle did have the UK vz.59 machine gun.

This is a late stage modification of the OT-62A, with around 80 being built, with around 36 mounting the Tarasnice 21 (T21) recoiless rifle.

This vehicle would have high crew member count, with 6 being present inside the vehicle. These crew members being gunner, 2 loaders, commander, driver and machine gunner inside the small turret.
