I've played this one the most since one can finish inside of 2 hours, including setup. The other scenarios, add reinforcements from other Western nations, and for the Iranis, and Sov. intervention. The tact situation facing the invaders is interesting. This game is very solitaire-playable as well do to it's mechanics. There's also standard supply and VP noting as well.
Units then recover and a new cycle begins.
As I noted, there are two cycles to a turn. A unit expends diff. All options are supported by simple on-map charts and tracks. So unlike other games at this scale, one can't move and fight with everyone all at once. Attacks develop, fail or succeed and can be reinforced, or exploited.
