It was played in Alpha Strike, which means turns are 30 seconds, and you either hit with everything or you miss with everything. The Dire Wolf has something like 10 armor and 6 structure, and shoots for 6 damage at short range, 7 damage at medium range, and 5 damage at long range. My Jager had 7 armor and 5 structure, but shot 4/4/4.
It took four turns. He missed twice. I didn't.
By the end of it my Jager had half MP and was missing half of its firepower, but by God it limped away and left the Dire Wolf a smoking pile of wreckage.
EDIT: The shot that took it down was the last shot taken on the last turn of the game, and the kill was enough points (by two, out of 500) to give us the win for the scenario. Go, mighty Jagermech. Go and prosper.
