what time period is the most even for US vs USSR?

I also agree wholeheartedly with Don's comments on the 1960 thru 1980ish period. The new weapons systems introduced by both sides during this period make for very interesting battles, you really need to take advantage of whatever advantage the side you're playing has.

I like the 1970-1975ish period best myself. IF you create a Player VS AI campaign and equip yourself with all top-of-the-line weapons systems the AI will tend to use a few top-end systems and large number of 2nd-line ones making for interesting battles as you have to deal with both quality and quantity in most battles.
