It's supposed to represent Polish resistance and the Warsaw Uprising, some soldiers made makeshift flamethrowers if photographs are to be believed.
Sure the Uprising was only a brief event, but it would be fun to play as Polish resistance forces. It'd be more related to the Eastern Front than the RMC (As much as I like the RMC). To me, Partisans only cover part of that right now.
But moral issues might come into part with Axis players finding themselves needing to fight the resistance, if they're concerned with that sort of thing.
