I support OC laws and I hope lots of folks OC. But I won’t.
Let me see if I can articulate this right...
In the military, you try to be as menacing and devastating as possible. You aren't out to just kill your enemy, you want to destroy his ability to fight back. This is most effective if you simply break his WILL to fight. One man armed with a rock can still fight, if his will to do so is intact.
In battle, you use a number of tactics to evade or engage the enemy to hit him where he is weakest. To catch him off guard. Snipers, SEAL teams, and even fireteams in combat movement try to catch their opponents unawares and vulnerable to attack.
This does not translate back into the regular civilian world. Most criminals are like water, they seek their level via the path of least resistance. They don't hunt down the strongest points of resistance and ambush them. Only the truly psychotic do so and are a danger no matter what precautions you take.
I was never in a combat unit, but even aviation Marines are taught the basics. My theory may not be fully elucidated here, but I think the bones of the reasoning are pretty sound.
