This quick little video shows how easy it is to fire from the hip in the ArmA2 engine. For those that don’t know, firing from the hip means that you do not raise the gun and look down the iron sights, or in the scope. You simply learn where the bullets come out (for most games it’s the center of the screen, in ArmA2 bullets exit from the gun barrel itself.
Knowing this should make you better at firing from the hip which can save your ass in a firefight. Sometimes it isn’t quick enough to raise the iron sights. For example, if you run around a blind corner (tip #2 – don’t run around blind corners!) and an enemy is right there a couple meters away you have to fire from the hip.
