We played the first scenario in the Seelowe manual. We agreed to let me use the Jagdluther for 50 points. We agreed in the following stats for it:
Move= 1
Armor= 5
Health= 6
I kept it on the far side of the deployment zone, along with a Ludwig and a Heinrich, for support. As the enemy deployed, the Jagluther was immune to the fire from Mickeys, and killed 3 of them, one after the other, before it was killed by Rosie and a sniper squad.
Overall I feel that the Jagdluther with these stats performed well. If the enemy had fielded a Pounder or a Hot Dog, I believe he would have killed it faster.
