You have to wait for the number of turns, so there could be a counter attack before the game ends.
Yes, this. I was ready to pack up and end the mission having secured my objectives when I discovered the number of turns was fixed at 10 (and not "up to 10"). So I played a further three turns, and on the last turn a counter attack left me in a losing position. No problem, though. It just meant I got the fun of replaying the scenario again (this time with some units already in position).
