Two US M5 Stuart & a Soviet T-26 (1933/35 era) turrets but I'm not picking the hull
Has that Soviet look ... in a multi-turret over-kill sorta way.
The base for the hull is a Leopard II hull, up side down - cut and sanded flat
Scratch ribs and thin sheet plastic bent and formed to shape
It was not going to have a dozer blade, but I could not get the front corners to look right, so.....
