More killing. Less good deeds

[William F. Owen]

I've never heard of any opinions saying that the Wermacht's success in Europe (I'm thinking of Yugoslavia and the occupied Soviet territories in particular) as being threatened by insurgency, but rather the resistance movements serving solely to tie down fighting troops.

I'd skip the Wermacht as a reference point except to show that irregular and regular warfare can exist in the same conflict and that there are irregular conflicts which are nothing to do with insurgencies.

Point being, no one should fix an understanding of irregular warfare based on Iraq and Afghanistan. There are many other conflicts, with critically different contexts.
