Id love to get mines, but I have to pay 110 manpower for every mine I deploy outside of the terror doctrine! This is one of the things that irks me the most about wehrmacht in EIRR that blitz and def are denied the ability field an equal amount of mines for manpower. In vcoh mines are integral to fighting off early motorpool, yet here a piosquad only gets 1 mine in these doctrines.
Try playing Brits.
180 manpower, and 70 munitions just to get a single mine (and demo).
