I've been watching a lot of western movies lately, and I'm just in the dollar trilogy at the moment. Often in gun fights, person A will asked his partner in crime, "cover me", so person A can move swiftly to a different location without being shot at.
But what exactly is the partner supposed to do as "covering"? Keep shooting random shots at enemies, or accurate shots at the moment sensing Person A might just be shot at? If the former is correct, why bother asking for covering surely that's what gun fights are about, you just keep shooting at enemies until running out of ammo or defeating enemies?
Just one more, seems like saying "cover me" gives you that immunity. I cannot recall anyone saying " cover me" will end up dead while they hop across a gun fight.
