Well... it is not just the writer of an article, but the people who do the edits... the article on the Battle of Ismailia (with T-55 to stay in theme) is quite funny even confusing places on the west bank of the Canal with places on the East Bank and suddenly having an airbase near Cairo popping out as it was near Ismailia... well it is wiki after all... I tend to use it for the plot of movies and videogames... ahahahah...
Now back to T-72. I have checked the SIPRI database of arm transfer and they never got to Vietnam... even T-62 were supplied after the fall of Saigon, yet Chris is wrong in saying Hanoi was a second rate client, it was quite close to Moscow (they got pretty high quality air defence stuff, not that they did any good when the SAC finally got its ass in shape on 26 December and well in 1973 it was the PAVN who had been humiliated and Hanoi crying... but these are details). Hanoi leadership was quite close to Moscow anyway and become closer and closer after 75 plus they provided Moscow with decent port facilities in the South China sea. The main problem for soviet supplies was the need to bargain with China for overland transfer and to use a single port that in the end got shut down by the USN; so there was a need of prioritize stuff. Air defence equipment and artillery seemed to have made up the bulk of Soviet deliveries with tanks mainly coming from China (thus a lot of Type 59).
Also I have doubt that sending the -72 to Vietnam would have made sense. it was new, untested, probably too cramped for the climate and the autoloader system and cartridge seem to have shared the same humidity problem of the Sheridan cases. But no one on Wiki seems to have thought about that...
allied tanks in Vietnam were only M48, M41, M551 (more than a brief stint), Centurions, and a couple of dozens of M24... I know the AVLB and M728 but their are not tanks and no M60A1 ever shipped, they were reserved for Europe and CONUS formations.
Thanks for the tip on Petner's Panzers. Well I think that for the -72 I will have to stick with QRF and the new Zvezda...
