In 2009, the U.S. Marine Corps selected the Trijicon ACOG® 3.5×35 TA11 as its Squad automatic-weapon Day Optic (SDO).
The SDO will mount on the M249 light machinegun to assist gunners in target detection, recognition and identification.
This model includes the Trijicon® RMR, providing the operator with quick target acquisition at close quarter distances or when vehicular mounted.
