God bless the old M2!! One of the oldest and most effective weapons in Army inventory.Don't believe it's been mentioned in any of the conventions.Don't think anybody we've fought since WWII signed either the Geneva or Haig conventions anyway.

Is it posible that someone believes that death by flamethrower,napalm,bayonett,entrenching tool or teeth is somehow more "humane" than death by .50cal. ?

BTW the .50 is not capable of handling more than light armor.Won't do much with a tank.
