Summary: The article says the M16A4, adopted in 1997 and used by Marines in conflicts such as Fallujah, Ramadi, and Helmand, was accurate and reliable but optimized for long-range marksmanship. It argues the rifle was built for one kind of fight and was deployed to another, leading Marines to trade the M16A4 for the M4.
WHO: 19FortyFive (article author/analysis)
WHAT: The article explains why Marines moved from the M16A4 Service Rifle to the M4 carbine.
WHEN: 1997
