In ArmA 3 it would be very helpful if their was a melee ability. It could be very useful in certain CQC engagements especially if the player runs out of ammo or if the enemy ends up being right in front of the player when entering a room. I am not asking to add a knifes into the the game just the ability to smack enemies down with your gun. This kind of attack can be found in many games including very realities ones such as Americans Army 3.
