This is the ‘MAS MENOS’ Flight Suit Sleeve (Pencil Pocket) patch for the 47STUS (one of the USAF Pilot Training Squadrons) located at Laughlin AFB, TX (Del Rio, TX) and means “The explanation seemed more or less clear to me”. Having been in some of these briefings as a student and as an instructor, that term came up MANY times when one of us was confused and the other wasn’t!!! This patch DOES have velcro attached.
