Laser Guidance system has been added to the Ostheer Mortar it seems.
wrong. they had it all along.
it's just you. Try the other faction, build a mortar, see how "laser-guided" it is.
many times as soviet (10~20 times), i built my own 82mm and stole enemies' 81mm. almost always (except in 1 game) the german mortar got vet faster while 82mm just sat there try to catch up.
