Spent around 15 months as a M2 gunner, and I'm pretty sure I can speak for anyone who's ever been a 50-gunner in saying you'd be told in a heartbeat to fuck off and die in a fire if you told me I had to lug that thing around on foot. M2+tripod weights around 120-130lbs (~55KG). Each 100 round can of ammo comes in at around another 30-35lbs. The way it's employed in game is laughable from a real-world perspective.
In-game however, I love using the 50 to support rifle pushes/hold a position temporarily.
I can acknowledge his information given, also spent some time firing this weapon. I am glad I had it mounted on a vehicle though.
Main idea about this weapon is it disables light vehicles and shreds up infantry a lot.
Basically if you get hit by a .50 caliber bullet, you'd be splashing to bits.
it is in-game not even close compared to the real life version.
