M16's are fun to fire, but jam up a lot. i def would not want one if sent to battle. M60's are fun, but heavy to carry, and you need a buddy to feed ya rounds so its essentially a 2 person job unless your built like Ahnold. 50 Caliber. Very fun. Not very portable, but packs a helluva punch. Good for taking out tanks and such. It is however against the Geneve Conventions to fire these @ personnel, you can only fire them at equipment, so in the words of our illustrious Commander, fire at their belt buckle! M203 Grenade Launcher - paired with M16, its a cool tool, but like the M16, jams up a bit, and I dont like grenades getting jammed in my hands. AT4 - Not really a gun, but is a line guided anti tank weapon. Good if you;re in the hood and some punks are bothering you. Just like the one Michael Douglas used in Falling Down. S&W 9mm - the pistol of choice for US Army commanders. accurate light, easy 2 maneuver, and resists jamming. I've fired em all, and well dont care to ever fire another one again. They're loud and smell yucky.
