Who is Staf Sergeant Don. F. Browne from Bloods: An Oral History of the Vietnam War by Black Veterans and what is their importance?

Don is already career military by the time he is sent to Vietnam. He joined the Air Force after flunking out of Howard University. Don wanted to be a pilot but bad eyes and failure to pass the written test kept him from qualifying. Instead Don works as an escort for VIPs at the American Embassy in Vietnam.
