I think you guys are really misunderstanding the realities of a gun fight. Maneuver (IE dudes coming to roll you up) is countered by a volume of fire, not really accuracy or range. We exchange literal thousands of rounds in a simple meeting encounter with small 2-3 man shooter groups on the ground. And we kill little/nothing most of the time because the reality is you rarely if ever hit what you’re aiming at whether it’s aimed well or aimed poorly. That’s why a handgun and a couple mags is a joke. About all the resistance you can be expected to put up with that is suitable for some farmer stumbling on your RAZ and trying to take you to the local authorities because he found out you killed one of his chickens. Look back at Vietnam and Desert Storm, name me any incident where a crew member successfully fought it out on the ground alone and unafraid with a handgun. You need noise, you need ammo, and you need persistence of creating a feeling of “I’d better be F’ing worth it to you Hadj!” Because they will overwhelm you. That is going to happen whether you’re down there with a 9mm, a M4, or a 240B. The only difference is the motivation for them to wait a few more minutes that is provided by a persistent defense. Durant had an MP5K, 4 mags, 2 Delta Snipers with full combat load, and all the left over mags and ammo scattered around the wreckage of that Blackhawk.... all that did was buy them minutes. Even if the DC powered GAU had been working, eventually the horde is gonna come get you.
