Iraqi errors report - Part 2

[Marcello]

Basic T-55 retained the BMG, which was deleted in T-54A

That should have been T-55A instead of T-54A.
The basic T-55 was the only main varian without AAMG, as both the previous T-54s variants and the following T-55A had them (the Dshk had ceased to be considered useful against modern aircrafts and helicopters were not yet considered a major threat, plus the whole NBC issues).
