August 18, 2005: The fighting in Iraq is taking a toll on the assault rifles and light machine-guns that do most of the shooting. So the U.S. Department of Defense has ordered another 50,881 M-4 assault rifles, at $1,042 each, and another M249 Squad Automatic Weapon (SAW) 5.56-mm light machine guns, at $667 each. The M-4 is a short barrel M-16, which makes it easier to use from inside a vehicle, or when fighting inside a building. The M249 is basically an M-16 design modified with a heavier (and easy to change) barrel, and the ability to use belted ammunition. The M249 provides most of the firepower for the infantry, with each fire team of 4-5 troops having one M249, over a thousand rounds of belted ammo and one or two additional barrels (when the M249 barrel gets overheated from firing too many rounds too quickly, a fresh one can be installed within seconds.) The U.S. Army wants a new design for their light machine-gun, partly because the M249 (introduced in the early 1980s) was wearing out. But the heavy use of M249s in Iraq and Afghanistan has resulted in a need for new weapons, before a new design can be agreed on and put into production.
Is something wrong with this picture? Are the prices reversed or do the M4 packages include optics? This is from Strategy Page and I've never seen a technical mistake in one of their articles before.
