>>4295472>The Abrams M1 uses the same 120mm Rheinmetall gun as the Leopard 2, and has interchangeable ammunition.The M1A1 and M1A2 both use the L/44 which has a shorter barrel and a lower shell velocity than the Leopard's L/55
>The Russian T90As have a top speed of 60kmh and a maximum range of 550km. Weighs 46 tonnesTop speed shouldn't shouldn't play much of a factor when it comes to range.
>The Leopard 2 has a top speed of 68 kmh and a maximum range of 550km. Weighs 62 tonnesThis is correct and I apologise for not checking this myself earlier.
>The Abrams M1A1 has a top speed of 72 kmh and a maximum range of 490km. Weighs 72 tonnesWhere are you getting your facts from? The M1A1 weighs 63 tons. The M1A2 weighs closer to what you state. I can't find anything that says the M1A1 or M1A2 has an operational range of 490km
>The T90As are mass produced to be easy to make in great numbers, not to win wars with their quality.This is correct, but it doesn't mean the T-90 is outmatched in every aspect.
