Best late war German arty for counter battery?

I'm going to have to agree with every one else. I use the 17cm gun for exclusive counter-battery fire. You have to have it in your core though because the experience gained will greatly increase the chances of you getting a counter battery barrage. I always buy one section of 4 guns as part of my original core for just this reason.

Yep. Buy off-map artillery to your core. Experience (and range) is the key here.

Concur 0n the 17cm it's one of my first buys in any core
