RE: "the wounded attackers"
"That's when a good knife comes in handy...it saves on ammo. "Having seen battlefield wounded Abu Sayef in the Phillipines during Operation Freedom Eagle and Al-Shabaab/ICU on "the Horn", I can tell you this: I will NEVER, EVER approach a wounded human that was attacking me
You either dispatch them with a bayonet or better yet, a hatchet/axe to the head if they are unconcious, or at range with a firearm if semi-concious.
There is no more dangerous organism on earth than a wounded human. Superhuman strength, knowledge of impending death, and just plain primal meaness wanting to finish their mission on taking you out. Never give them a chance. NEVER.
The only caveat is if you absolutely need intel from them; if so, you better brush up on your EPW search/security techniques....and be in top physical shape to restrain someone that comes out of an adrenaline-filled last bolt of life!
You are 100% right never ever approach a conscious wounded human who was just moments before intent on killing you. That is exactly why I said bayonet them you still have a hot round ready at point blank range to the head should they attempt to fight if they move pull the trigger. As for the axe we carried all steel tomahawks 18 inches long with an edged side and a 6 inch spire side. It is truly surprising how many different things can be done with a tomahawk. They also would be perfect for dispatching semi-conscious point side to the small of the back of the head. IF you need intel then have some MP trained guys around they have all be through EPW training..a blowtorch and some pliers will get you all the intel any one needs. We were not implicitly authorized to have Ruger Mark 4s but they sure do make a good sentry dispatch weapon when suppressed at point blank range.
