Sorry, OT here. But it reminds me of a game I played in 1991, which is Special Forces.

That Microprose game was great IMHO. I needed to use joystick to play it properly, and I could not finish some of the missions, but still it was a nice experience
k:
I don't think it is the game you're looking for, and even if it is it will be ESA-protected since it is made by Microprose. So, sorry again for being OT here
