Bought this on GOG as soon as it was released, having already owned it on Steam - thank you Microprose and Dev for bringing it to GOG. This is a single-player focused RTS set in recent history during the cold war. If you've played any of the Eugen Systems Wargame series, you will have a flavour of what you are getting here. If not, then just grab this and enjoy! Game modes include skirmish (different ways to win), and operations (essentially story-based scenarios).
I don't own this on GoG (bought it on release back in the 90s), and no intention to buy it now, even if on sale for 10 cents. I'd genuinely debate whether or not it was worth adding to my library if free. It looked great and promised a lot. But the AI was the worst I've seen in any wargame, period. It just sat there. If you attacked, it didn't respond. If it was on the offensive, it didn't attack. I remember the response of Microprose way-back-when I contacted them about this, thinking it was a bug and would be fixed "We know there are problems with the AI, suggest you command at the highest level" - in other words, turn a game that promised the ability to "command thousands of troops" into a game where you commanded 3-5 flags. Not that that fixed the AI problem, it just meant you couldn't micromanage to achieve 100% kill with 0% casualties against a completely useless AI.
