There is one one way to get to the sleeping areas, and it is a perfect ambush/killing field for me. A BG would need to use a frag to dislodge me, he would be able to advance with a flash bang, but that would put him in front of any of six doors I could be behind, two of which would be
behind him. I just can't see utilizing a knife in such a setting. It would place me at a huge disadvantage. I view a knife primarily as an offensive weapon (quiet sentry removal) or a defensive weapon of last resort, or something to grab just to be armed until I could get to my HD shotgun, rifle or pistol. But, if it works for you, great!
Something to consider, though:
While it is true knife wounds are generally more fatal, they are rarely
immediately incapacitating, even a femoral artery wound won' t cause incapacitating shock immediately, it can be from 5 seconds up to a minute, on a drugged up, drunk, adernaline crazed stabee. One can fire a lot of rounds off in that time, and while it would be a Pyrric victory, the stabber could possibly be just as dead. I've done Tueller drills helping my Dad train, (he was a cop), and while I studied knife fighting techniques, and weapon retention/disarming techniques also, whichever of us had the gun, (pistol or shotgun) would always get a COM shot off. Since the guns just had snap caps in, we could only get one shot off in training. In a real situation, I'd keep firing until I and or he went down. Yes, the knife weilder
always got
one slash in, and usually a fatal one at that but they were shot about 75% of the time within 2 seconds after the slash, 100% within 5 seconds.
The one time I faced down a knife wielding drunk who was insinuating the friend I was with should die because enemy soldiers of the same ethnic group killed his father in Vietnam, he was 15 feet from me when I drew my 6" .357 from the shoulder holster. Fortunately for both of us, he decided to drop the knife. He was drunk enough that he could not have got a slash in before I dropped him with 125 gr. JHP's. I did not want to shoot him, I went to school with him. About two weeks later, I saw him and after apologizing profusely, he asked if I would have really shot him.
I cryptically replied, "What do you think?"
