MAG-11 Security Guard Shield & Motto: "Sleep Tight We're Out Tonight".
I don't think this is an official Marine Corps logo or patch.
This one installed over the entrance to the guard shack is the only one I've ever seen.
Too bad! It represents us grunts better than the air wing patch that came up when I began building this profile.
The existing MAG-11 patch does not represent what we did. We manned a security perimeter around the air base.
