The letters FBI make a great point of reference when targeting, just aim slightly up..
Everyone needs to understand how to engage targets wearing body armor. Criminals will eventually have it so best to learn the signs of it and how to neutralize targets wearing it. Not sure any threads have been posted on it. Your comment made me think about it. Criminals wearing uniforms and armor will become more common as the country falls into lawlessness.
Does the military train for opponents wearing ballistic armor? 5.56 will not penetrate it. The new rifle and round will.
This is not a comment against legal law enforcement personnel doing their duties so please do not accuse me of that.
