Decided to separate my batch of older battle tanks from a previous picture into variants. And yes, these are in fact unmodified Centurion tanks in different variants with new paint jobs.

The SR-1 Kirov Battle Tank, first of San Cloe's class of main battle tanks. Most of these have been upgraded to SR-1A or SR-1B class, while the rest are in storage.

The SR-1B is modified with a new turret, main gun, coaxial gun, and a commander's machine gun. It currently serves as one of the primary tanks in the Republic.
