Matthew Schehl writes the Marines will use the M4 as the primary personal rifle at supporting schools, security forces and infantry battalions by September 2016.
Sgt. Jonathan Ferriera, a mortarman with 1st Battalion of the 8th Marines, told the publication that M4 carbine is smaller than M16 rifles.
âSize makes all the difference, because everything revolves around mobility and speed,â Ferriera said.
Schehl reports non-infantry personnel within the service branch will continue to use M16A4 rifles.
