The 4133d Bombardment Wing (Provisional) (SAC) has been established to support the United States Air Force operations in Southeast Asia, Its principle task has been the destruction of the Viet Cong. The Wing escutcheon depicts this function.
Depicted within the Air Force shield are two SAC mailed fists which symbolize the combined forces of the 484th Bombardment Wing and the 28th Bombardment Wing for strikes against the Viet Cong. Inscribed against a background of red (North Viet Nam) and green (South Viet Nam), the two fists portray the united efforts of flight, ground, and administrative personnel who have been equipped and trained to accomplish the mission of crushing the red "VC". The horizontal line separating the red and green background symbolizes the 17th parallel, dividing Viet Nam into North and South.
The target area, VIET NAM, is inscribed into the woven cord above the shield. The alternating red and yellow are the national colors of Viet Nam.
A black silhouette of the B-52 calls attention to the camouflaged aircraft being used by the 4133d Bombardment Wing. A bomb blast emanates from the aircraft to designate the first B-52 strike into North Viet Nam. The compass "N" at the top of the shield emphasises this historic mission against the Viet Cong.
The name BLACK BARONS inscribed on the bottom scroll is derived from the black aircraft and noblemen associated with the 28th and 484th Bombardment Wings in their war against the communist Viet Cong.
