What the Warsaw Pact had was numbers. For it's time, tech-wise, the T-72 would've been going against the M60, later the M-1. The Pact also had air defense artillery in spades..........from MANPADs, to light/medium AAA, to mobile SAMS [only talking about the mobile ADA pieces, not even getting into the fixed, heavy stuff]. At the time, the A-10 was thought to have about a 2 missionsurvival rate, with all the ZSU-23s running around. For ADA, we had the Chapparal with its AIM-9s, and the M163 Vulcans, with some M42 Dusters here and there. Pact would have their own Frogfoots doing work on the front lines and against our ADA, troops, and tanks; as well as our AH-1s/AH-64 helos, going against Mi-24 Hind, Mi-28 Havoc, and the kickass Ka-50 Hokum helos. Tactical nukes were already sitting alert with Britain-based F-111s, as well as Germany-based F-16s; and thats not even including the Britain-based, USAF-operated GLCM medium range missiles, or the Germany-based, US Army-operated Pershing-2 missiles.
It would've been a mess, likely with no real winner. Because when it comes to nukes.....when one flies, they ALL fly.
