Two points here.
1. People say MG42 is best MG in the game.What they often neglect to even consider, is the amount of set up and take down time they require. This means you must either set them up in advance or with units ahead of them which leads me to my second point.
2. Support. Some of you above mentioned that "OKW still managed to destroy my MG team frontally. This happens to ALL unsupported mgs not just allied ones. MG42s many times get mowed down by riflemen and will die before they can pack up or retreat. You will be amazed at how well your mgs perform if they can see and pin their enemies whilst firing at max range and before the enemy can even see them. A number of patches ago they buffed pios LOS IN ORDER TO HELP SPOT FOR MG 42s. Along with this was an accuracy far buff which helped a ton.
Maxims have a smaller arc of fire but they also set up almost instantly. This is SUPER useful to use in conjunction with other infantry units because you simply A move them at the enemy with your other infantry spotting for it.
Use MGs against OKW. But NOT by themselves. There is a reason it's considered a "SUPPORT" unit.
Well, you can't "sweep" demo, and demo is not automatic like mines so there is no discuss about demos giving vet
I can imagine, that disarming whole s-mine field would give around 30% of exp bar, same for teller or M20 mines, while OKW, SU and Brits mines would provide 15% of the bar.
That sounds fair. Id say give them even more vet from sweeping but less from making kills.
