This would of course come as news to the Russians, who absolutely creamed the much-higher-tech Germans in WW2. It turns out that five lower-tech tanks that start reliably are worth more than one high-tech tank that doesn't.

It's also worth noting that none of the technologies you list have ever been deployed in the field against a real peer competitor, and many have never been used in combat in the roles they were originally intended for. (The F-15 was designed as an interceptor, for instance, but in actual combat has mostly been used as a strike fighter. The M1 was designed to fight Soviet T-72 and T-80 tanks, which it has never had a chance to do -- even at the one real armor battle it has taken part in, the Battle of 73 Easting in 1991, it faced less capable export-version T-72s alongside older T-55 and T-62 derivatives.)
