They are crazy!
They use burst mode at NCR, shooting at outlaw+at poor random guys near, they usually kill 1-2 innocent before they kill target.
First they use single shot, and if target is still alive, then they getting fun by bursting everyone who's near target.
Suggestion: Prevent guards from using burst mode? Because it's almost like Boneyard Fortress now where you punch someone outside and guards with bazookas and grenades killing you and everyone near you, but at NCR now it's less AoE and you need to survive all single shots from all guards, so they start to burst you after and kill some innocent, actually it's fun, but anyway it doesn't seems right.
