There is no reason for name calling on this forum. Certain norms should be maintained, we are all here to learn and have fun without belittling each other. Comparing Soviet records from 1939 (then a local conflict) and from 1945 (full swing WWII after several major changes and reorganizations of the Soviet war machine) is a basic mistake. Early records could be lost or destroyed, let alone put on certain websites as of yet and so on. A lot can be said about the Soviet Red Army but that 'they did not report their losses' cannot. Their personnel and material losses were reported in different channels (unlike the American MAC Reports, where both were reported in a common folder), not to mention that their records were overlapping in a network of multiple documents. Regiment, Division, Corps, Army level, etc… These documents these days can be found at TsAMO RF with a portion published online (mostly unit diaries). Aircraft losses and mechanical records are also kept there but most of them are not published online.
But let us get back to Hartmann…June 4, 1944 is interesting to say the least.
