3rd Vietnamese Battalion ‐ 1952
Sent in June 1952, this cover represents a very early Vietnamese unit, identified as the 3rd Vietnamese Battalion by the red hand‐stamped cachet.
The sender includes his SP number (Secteur Postal = Postal Sector or Zone) as well as his BPM number (Bureaux Postaux Militaires).
BPM 402A was located in Cantho between January 1951 and March 1955.
A Sector Postal was the equivalent of the American A.P.O. address and had five digits.
The 4‐digit number “4012” on this cover is a actually a Vietnamese KBC zone number, despite the French designation.
