Light Tank Stingray.
The Stingray light tank possesses well-sloped armor, and its suspension's similarity to that of the M109 self-propelled howitzer is evident. The relatively small size of the vehicle can be gleaned by the scale of the TC's .50cal MG. Note the muzzle brake design, which helps to allow such a light machine handle the recoil of its 105mm gun.
