I probably should do that b/c I'm totally blanking on swastika tits.
Also, couldn't the non-lethal tank fire rubber bullets and flash rounds to scare the baddies? You got me on the cannon though...unless it shoots those bean-bag thingies cops sometimes use. However, I do seem to recall 'splosions...but I don't even rightly remember swastika tits, so my memory isn't a valid source on this by any means.
