The problem is not about what kind of tank or other armament we have, but against who and when, and in which conditions we can use them. And when we must use them, we must receive superiority on the battlefield. Against who we can use our tanks? Look aronund, and we had not much posibilities. And in every one of them, TR-85 M1 is enough to give us tactical superiority, if they will be in sufficient number. And if the other weapons were ready to use. And if the capability of other army branches were ready to do their job. And many if's.
The rest is tactics, strategy, and, later, history...
