Their numbers vary depending upon source, and so far the crew of the A-20,
the two MiGs from the 83th IAK shot down in November 1952, and the passengers
and crew on the Il-14 are not counted.
They also do or do not count training losses, depending on source. That said,
the numbers are "roughly right" for combat losses. They did not indicate how
many other casualties they took from disease or injury.
Many pilots were medevacked due to stress and fatigue from jet combat without
"G" suits. This was considered a badge of shame for some reason, and most
tried to gut it out and lie to flight surgeons.
The bulk of the combat casualites were the AA gunners on the ground near
prime targets or airfields.
