No, a.50 caliber machine gun is used as turrets on armored vehicles or used on
military bases for security. There is a reason you never have someone holding one of these because you simply can't, and if you could you might lift it for a couple secounds before getting tired. The anti tank rifle won't do anything usefull, it will only blow off body parts leaving them still running after you.
For those of you just now posting these horrible lists, read the OP, its things that you could likely get your hands on in the middle of the chaos.
