I'd say you should still try to get a calliope on this map. It's really strong, since the callipe can fire out of the base into the enemy base, hence you don't need to expose it to danger. AT wise you need to rely on AT guns and zooks, till you can afford a jackson. That shouldn't be a problem.
I personally veto this as OKW simply because of the Calliope, it's sooo strong here.
