3rd ID soldier: “I know it fires very well and accurate [when] clean. But sometimes it needs to fire dirty well too.”
25th Infantry Division soldier: “The M4 Weapon in the deserts of Iraq and Afghanistan was quick to malfunction when a little sand got in the weapon. Trying to keep it clean, sand free was impossible while on patrols or firefights.”
82nd Airborne Division soldier: “The M4 is overall an excellent weapon, however the flaw of its sensitivity to dirt and powder residue needs to be corrected. True to fact, cleaning will help. Daily assigned tasks, and nonregular hours in tactical situations do not always warrant the necessary time required for effective cleaning.”
75th Ranger Regiment member, SOCOM: “Even with the dust cover closed and magazine in the well, sand gets all inside; on and around the bolt. It still fires, but after a while the sand works its way all through the gun and jams start.”
The 507th Maintenance Company, ambushed outside Nasariyah in 2003 during the opening days of the ground invasion of Iraq, might concur with all of the above. The post-incident report released by the US Army had this to say:
“Dusty, desert conditions do require vigilance in weapons maintenance… However, it is imperative to remember that at the time of the attack, the 507th had spent more than two days on the move, with little rest and time to conduct vehicle repair and recovery operations.”
Even without those extenuating circumstances, however, there have been problems. A December 2006 survey, conducted on behalf of the Army by CNA Corp., conducted over 2,600 interviews with Soldiers returning from combat duty. The M4 received a number of strong requests from M-16 users, who liked its smaller profile. Among M4 users, however, 19% of said they experienced stoppages in combat – and almost 20% of those said they were “unable to engage the target with that weapon during a significant portion of or the entire firefight after performing immediate or remedial action to clear the stoppage.” The report adds that “Those who attached accessories to their weapon were more likely to experience stoppages, regardless of how the accessories were attached [including via official means like rail mounts].” Since “accessories” can include items like night sights, flashlights, etc., their use is not expected to go away any time soon.
