I have available this amazing handmade communications flag from the Vietnam war. The flag measures 17 inches wide by 11 inches tall. It is double sided. This appears to be a handmade military platoon guidon (unit flag) rather than an official issued flag.
The markings likely read:
“BLT COMM PLT 3/8”
* BLT = Battalion Landing Team * COMM PLT = Communications Platoon * 3/8 = 3rd Battalion, 8th Marines, a unit of the U.S. Marine Corps
The center artwork appears to feature communications-related imagery (radio/signal equipment, antenna, plotting or communications graphics), which fits a Communications Platoon theme.
Please view my photos and email me with questions.
