A Marine's account of an ambush in Iraq:
I flipped the selector switch on my M-4 rifle from SAFE past FIRE to BURST. I had never been allowed to use BURST mode during training. This seemed like an appropriate time to start. I peered through my EOTECH optical sight, looking for the source of the fire. I heard a Marine from First Recon open fire with his M-249 SAW machine gun from the roof of the house, applying 800 rounds per minute of crunchy 5.56-millimeter goodness to some unknown target. From my vantage point I could only see some houses about 300 meters distant, but no muzzle flashes or indications of the gunfire. I considered putting suppressive fire on the rooftops of the buildings, which was the most likely location of our assailants. However, I could not positively identify my target, and our rules of engagement required that before I opened fire.NYT.
