Its fine, OKW mine sweeper needs the same range as all the other fractions. Buffing bazookas wont help that much seeing how the OKW puma has both sight and smoke allowing it to get out of jail. Common sense in seeing an M20 is.... oh he's probably going to mine somewhere. I should be cautious about getting baited into mines with my light vehicles and avoid roads and key junctions. I should get sweepers or I'll just skip building light vehicles go straight for obers and AT infantry units and steam roll everything and get my heavy tanks to finish the game.
Ya its pretty cool seeing how this unit punishes any allied player who tries to use combined arms allowing the horde of vetted axis infantry to steam roll anything else that is left. Stealing an abandoned one is just as good as stealing strumtiger or kubal and using it on an OKW player.
I've also had american frags not function. It was frustrating...
When I first ran into the howi not working, I was like i'll build a howi to help clear out the axis defensive belt of mgs and paks, only to be greeted by it not barraging.... yes quiet irking.
