How bout "Brothers of war", "Operation Coverseige"? sounds a nice mission idea. how bout havin the 2 teams seprerated to add a bit of a tactical option? make shure if it is story based, unexpected occurances can happen, such as when you get quite close to the base, a russian convoy comes to stop off there to pick up goods. that would give the mission an unexpected twist since you didnt know another group was coming in. and maybe, when you get there, one of ur guys escpaed by himself on the convoy wile the other stayed behind? that would mean you have to follow the convoy in the next mission and rescue him from that one. that would keep it pretty fresh.
