Is it the 140mm version? Unusual 'camo'/

Still, could be found in warehouse somewhere and put into use...



Edit: It seems to be the "General Dynamics AbramsX".

120mm main gun...

The real-world 140mm Abrams was the CATTB (Component Advanced Technology Test Bed), which was fitted with the XM291 Advanced Tank Cannon. Its special deal was that the caliber could be changed in the field in an hour by swapping barrels, being either a 120mm L/55 or a 140mm L/47. There were 17 rounds in the turret either way, with the hull carrying either 22 of the 140mm rounds or 33 of the 120mm rounds. A bustle-mounted autoloader gave the tank an 8-10 round per minute fire rate. Armor was upgraded as well so that the turret front was 1250-1300mm RHAe and the turret sides were around 520mm RHAe.

The gun was tested in 1987-88, the overall tank (fitted with a Cummins diesel) was tested in 1990, and the collapse of the Soviet Union in 1991 killed the project.
