ok, my pros and cons:
MARINES! faithfull elite us marine corp:
pros:
rifles: m4 aimsight, easy to use, good for a sniper or support weapon, and great in close range. m4 standard, good to lay down cover fire, great in tight places. m16a2, very accurate rife,easy to use, burst fire capability, great for long distances. m14 sopmod sniper, very accurate, great caliber, easy to use scope, semi automatic. m249 squad automatic weapon (or S.A.W.), great magazine capacity, very accurate, compact, good for cqb building entry and clearing, and long range.
cons: m4 aimsight, cuts off line of sight in some places, making your surroundings difficult to see. m4 standard, iron sights can be tedious to use, long range is a bad idea. m16a2, iron sights are tedious, sometimes you cant get a good shot with the gun. m14 sopmod sniper, standing fire very hard to lay down multiple shots with the high recoil.
INS, dem ones willing to blow them self up ( never come into contact with me and a rpg, im a suicide bomber >

):
pros: ak 74u, high fire rate, great magazine capacity, accurate, compact, and great for long range and cqb (close quarters combat). Fn Fal: great for long range, semi automatic for good accurate shots. ak 47, a feared gun in the iraqie arsenal, good fire rate, great for long range, cqb, great caliber, and a very deadly stopping power shot, lee enfield, world known for great accurace and kill rate, accurate, semi automatic to make it a rifle worth sniping without a scope. rpk, great for cqb, long range, and a high magazine capacity accurate. Rocket Propelled Grenade 7 (RPG7), great building clearance weapon,great suicide bomber weapon, long range, takes out packs of foes.
cons: ak 74u, wood stalk and hand grip? breaks easy in a combat situation (in REAL LIFE, not game), maybe shoots a little too fast. Fn Fal, OUT DATED, iron sights are hard to aim through, takes skill to use. Ak 47, MASSIVE RECOIl. Lee Enfiled, OUT DATED, magazine is clip fed (aka eather single bullet loade, or a spead loader, mag is not detachable). RPK, massive recoil on full auto, too bulky and big. RPG, CLOSE RANGE SUICIDE BOMBING, not good for building entry unless your teamates are 20 feet back and you are in front.
