I dont see anything wrong with those videos. Mg42s shouldn't be able to kill anything or suppress from the front because they are not combat troops. They are support troops and should be doing things like peeling potatoes. They are more for recon if anything else.Your supposed to use your mg bullets to distract the enemy then rush in with your ostwinds. This makes the game fun because now you'll have to micro your mg and support it with air support and artillery.
I disagree. Mg should be MORE effective from the front, but less effective as it turns out to its arc. Charging mg's is ridiculous, and should not be encouraged.
Mg is not a recon unit. Mg is all about suppression, not necessarily killing outright.
