Sort of adding on to my previous thread about armor. Most of the people I know that own them ( 4 to be exact) are using Kevlar level III A. Terrific. But after trying one on that even had a liner, a realization hit. They may stop some rounds from penetrating the head, it doesn't seem like that light a helmet will stop anyone from getting clobbered, maybe a concussion or cracked skull, and certainly getting knocked out of action. While I can see them in a war zone, I don't know if they are worth the wear for the current city conflicts. Thoughts? Note to Exnordie- pretty sure there is nothing invasive here. I didn't ask about ownership or numbers. Just want to know people's thoughts on whether they are worthwhile in a non-war zone.
