Marksmanship, the ability to shoot accurately and service targets with the minimum expenditure of ammunition, has always been part of the Marine Corps ethos. The adoption of the M27 Infantry Automatic Rifle over the older M249 Squad Automatic Weapon marks a return to that ethos across the service at the small unit level. More accurate and capable of accomplishing its mission with fewer expended rounds, the M27 is now being considered as the front-line rifle not only for a handful of squad members but across the Corps’ front line units.
