Rare postally used local letter sent by a member of the military (note the Hom Thu number in the sender line) to Hanoi. The red stamp is cancelled with a dateless military cancel. Most local letters were destroyed in the multi-decadal war, the tropical climate and by recycling due to raw material shortages.
Another local letter showing the late usage of the red stamp on a letter from Hai Phong to Saigon in October of 1975 (shortly after the fall of Saigon). Hai Phong machine cancel. This may be a civilian use of the stamp as there is no indication of a Hom Thu or military unit number.

Military Free Franks without any nominal value were not valid for international postage according to UPU rules so they were only intended for domestic usage. Here is a very rare international express mail letter sent to Klewitz from Quan 5 in April of 1981. The letter features both perforation versions (11.0 & 12.5) of the blue military stamp and the red military stamp with the plate error “tank in action” along with other military stamps from the period. It appears that the stamps were accepted by the postal clerk without any issue and that they credited with a 12 xu nominal. The overall postage amounted to 14.76D (including the two red free franks). Kassel transit and Fulda arrival cancels on the reverse. Fragment of green Fukda custom cancel on front.
