Currently on offer here part of an image series covering the training period a Schlacht pilot with the Erg.Zerstörergruppe at Deblin (code 4M+), which became Erg.Schlachtgruppe at Deblin on 31.03.43 (letter with triangle). The aircraft above appears to be an old A-3 model..
More from the same unit Erg.Zerstörergruppe at Deblin (code 4M+), some of which were previously posted here in 2013. These fledgling Schlact pilots subsequently served with 3./SchG 1 (large letters in rear of the Balkenkreuze usually with a yellow theatre band). There are also some shots of planes from the Stab I./SchG 1.
Below; pilots of 6./SG 77 somewhere on the Oderfront towards the end of the war.
