D'85: BRM lacking Amphibious capability?

[Aaron]

But Leopard-I (105-mm gun) is weaker than T-64, T-72, T-80 (125-mm gun).Leopard-I worse armoured, and also has more out-of-date systems fire control.

Depends what variant of Leopard your talking about and what year, by 1989 i would say the Leo1A5, which armor wise had a better turret than everything up to a BV equip tank but the chassis was shite. Could barely stop a RPG. As for FCS well nothing the Soviets had could match the Leo1a5 till the T-80U. U can put a 188mm gun on a tank but if u cant hit anything who cares. Thats just one mans opinion im sure theres many more.
