(From the Squadron supplier): The 554th is one of only four active duty REDHORSE squadrons in the USAF and the only REDHORSE unit assigned to PACAF. REDHORSE stands for *Rapid Engineer Deployable Heavy Operational Repair Squadron Engineers* and are heavy-construction units. Their combat engineering capabilities are similar to those of the U.S. Navy Seabees and U.S. Army heavy-construction organizations. This patch does not come with velcro attached.
