A guidon is a pennant-shaped standard that signifies a particular unit. Modern U.S. Air Force guidons are ultramarine blue and yellow. The parent unit name appears at the top and the squadron name below. In the middle is an eagle.
This older guidon has a yellow vinyl eagle and numbers stitched onto dark blue fabric.
The 19th Tactical Airlift Squadron (TAS) was stationed at Tan Son Nhut AB in South Vietnam. The 19th TAS was assigned to the 315th Tactical Airlift Wing which was stationed at Phan Rang AB, South Vietnam.
The guidon’s donor, Colonel Charles Zemple, served in Vietnam from 1970-1971. He was the last commander of the 19th TAS.
