They had 55 armored divisions facing NATO's 5 (ours were M1s).
The Kremlin was confident in the Red Army. NATO was outnumbered 55:5.

And the Russian tactics didn't work, and their Russian tanks were blown to bits, and the Kremlin had to take a sober look at the exchange ratio of ALL the Russian tanks destroyed vs NONE of our M1s. Ditto, F-117s.
Any time you divide by zero, you're fu*ked.
