Using the new weight system, under King of the Hill games (KotH), most heavy weapons are now completely useless.
Using Navids, Lynxs, SPMGs, and launchers only works using a ghillie suit or other minimalist attire. The infantry base model no longer will allow this due to the new weight system. Simply walking often now raises fatigue to a point of uselessness, if you can walk at all.
Please advise server owners how to avoid/disable this system as soon as possible. This is the main mod of Arma 3 Multiplayer, currently ALL infantry are broken.
