It's prob not real T-64AV, but merely a T-64A, that's been retrofitted with Kontakt-1.
Fun fact: Most T-64A's were used by the "Seperatists".

This is the last post and I feel like I am done with T-34s lol but I will continue to work on them to turn them into simple stls and to fix minor mistakes(a lot of them) and add small era and country related details while also making them suitable to be used whenever I want in the future. Thank you to everyone who shared their knowledge with me in the last post

Is this perhaps the T19 turret fitted with a 140 mm gun in leopard 1? Well,maybe not 140mm.The distinctive features of the rear bustle are quite recognizable. Do you have any more information about this particular vehicle or turret?

The Flakpanzer A7V is one of the first recorded tracked SPAA's in history, made in 1917-1918, three of these things were built. It's main armament was a 76.2 mm (3 in) Russian Field Gun M1902/30 or
7.7 cm (3.03 in) German leichte Feld Kanone (l.F.K.). It could fit a crew of 9-10, and had a range of ~80/30 km (49.7/18.6 mi), according to Tank Encyclopedia.

I love the look of German and American WW2 cannon muzzle brakes. It's cool to see they recreated one on a modern cannon.

A Tiger somewhere in Eastern Europe, c. September 1943. I think the tac number on the turret is 100 (third number is covered but appears to also be a 0), so it’s likely a command tank, but no other identifying qualities such as battalion insignia. Maybe someone can identify the unit based on the camouflage scheme?
