Iraq Gun Porn: Which Guns Suck, Which Guns Rock
Which commonly used weapons in Iraq do our brave soldiers give the thumbs up to and which do they thumb their nose at? Here is a review.
1) The M-16 rifle : Thumbs down. Chronic jamming problems with the talcum powder like sand over there. The sand is everywhere. [The Marine] says you feel filthy 2 minutes after coming out of the shower. The M-4 carbine version is more popular because it’s lighter and shorter, but it has jamming problems also. They like the ability to mount the various optical gunsights and weapons lights on the picattiny rails, but the weapon itself is not great in a desert environment. They all hate the 5.56mm (.223) round. Poor penetration on the cinderblock structure common over there and even torso hits cant be reliably counted on to put the enemy down.
2) The M243 SAW (squad assault weapon): .223 cal. Drum fed light machine gun. Big thumbs down. Universally considered a piece of shit. Chronic jamming problems, most of which require partial disassembly. (that’s fun in the middle of a firefight).
3) The M9 Beretta 9mm: Mixed bag. Good gun, performs well in desert environment; but they all hate the 9mm cartridge. The use of handguns for self-defense is actually fairly common. Same old story on the 9mm: Bad guys hit multiple times and still in the fight.
4) Mossberg 12ga. Military shotgun: Works well, used frequently for clearing houses to good effect.
6) The M2 .50 cal heavy machine gun: Thumbs way, way up. “Ma deuce” is still worth her considerable weight in gold. The ultimate fight stopper, puts their dicks in the dirt every time. The most coveted weapon in-theater.
7) The ..45 pistol: Thumbs up. Still the best pistol round out there. Everybody authorized to carry a sidearm is trying to get their hands on one. With few exceptions, can reliably be expected to put ’em down with a torso hit. The special ops guys (who are doing most of the pistol work) use the HK military model and supposedly love it. The old government model .45’s are being re-issued en masse.
8) The M-14: Thumbs up. They are being re-issued in bulk, mostly in a modified version to special ops guys. Modifications include lightweight Kevlar stocks and low power red dot or ACOG sights. Very reliable in the sandy environment, and they love the 7.62 round.
11) The new body armor: Thumbs up. Relatively light at approx. 6 lbs. and can reliably be expected to soak up small shrapnel and even will stop an AK-47 round. The bad Hot as shit to wear, almost unbearable in the summer heat (which averages over 120 degrees). Also, the enemy now goes for head shots when ever possible. All the bullshit about the “old” body armor making our guys vulnerable to the IED’s was a non-starter. The IED explosions are enormous and body armor doesn’t make any difference at all in most cases.
