1. why cant all WH build tank traps? US can with all factions yet it was WH that was fighting a def war at this stage of the war. I think all Werhmacht factions should have tank traps available. leave it as is for PE.
2. tank trap/roadblock for CW RE and PE SE - they don't link well and thus many times there is a gap in between that vehicles can get through. tbh they are a bit rubbish at blocking except for specific choke points of right size like a bridge yet they need 1 CP to unlock. is there any way to fix this so that you can actually link them up and not have to worry about some gap vehicles get through? also wouldn't it be more appropriate if CW arty doc got this ability instead of CW RE doc?
