I never used the grenade launcher usually, but as I had an opportunity to really test his power I tried and they failed to destroy a single soviet building. I watched the grenade land in/on the tent and...nothing. I repeated it multiple times with more bombardier squads, 2 were level 4. I attacked the HQ with them and again they failed to destroy it even if it was about to collapse and a single shot from an anti-tank gun would have been enough.
As an unrelated side question, why don't the soviet anti-tank gun have 1 in power vs 2 for the ostheer?
