0321. To some it’s an insignificant string of numbers. To those in the know, 0321 is a rarefied designator referencing the #MOS (Military Occupational Specialty) for a Reconnaissance Marine in the United States Marine Corps. To those who are participating in an 0321 event, we wish you a day filled with camaraderie and community. In recognition of the day, the #USMC #GSAR from our #searchandrescuelineup will be 20% off until March 24 at 3PM ET.
