M1 Tank Factory

[raketenjagdpanzer]

I watched a documentary recently (I think it was originally linked to here in the forums) tank "building" "tools and dies" are multiple-ton, specialty machines, many of them computer controlled CNC machines. Nobody's going to build another tank factory. Not for multiple decades, not with a country with barely twenty million people left in it, who are starving, beset by plague, cut off by completely destroyed infrastructure, scattered across 4 million square miles with no remaining central gov't outside of a few enclaves and the gov't that's left is in a three-way de-facto civil war (all canon, btw.)
