Is Krakow as precariously balanced as it seems?

I'm running Free City of Krakow on my occasional Thursday night game, and I've been thinking about one mention in the module, that the 150+ strong band of marauders outside the city might want to try and topple it. Is that just their pie in the sky wishes or do they really think they could pull that off? I thought the ORMO in FCOK could squash the raiders! 150 of them, a single BMP-2, a few RPG rounds, 1 or 2 ATGMs...vs. the ORMO that consists of like 5300 troops, a short company of tanks (6 or 7 working T72s or 80s, IIRC), as well as a number of armored vehicles.

I would suggest that anyone thinking a group of 150 men and a lone armored vehicle poses a threat to Krakow's defenses needs to clean out their headgear.
