ah, nice photo. I can add a little something on Uffz. Basan here:
Date and place of action was 22.7.1944 at Radysche.
Also, I have found an old note from an visit of mine to the German Bundesarchiv in 2015, seeing file RH 39/661 (Rundbriefe from Pz.Jg.Ers.Abt. 20, Hamburg), the one from 19.10.1944 also mentions Uffz. Basan:
Uffz. Basan on security position with his schwere Pak. 4 T34 attacked, Uffz. Basan himself aiming the gun destroyed the first T34 at 200 m range, the second T34 was destroyed, standing behind a cemetery at 150 m range, than the third T34 was destroyed with an shot into the turret ring (Drehkranz), the forth T34 turned away and was killed with 3 shots at 600 m range. He just needed 8 shots within 8 to 9 minutes to achieve this success.
Another name from these "Rundbriefe":
Lt. Detjen was mentioned in the Rundbrief from 15.3.1943:
He was Führer of 1./Pz.Jg.Abt. 30 and within 4 weeks was able to destroy 6 tanks as a Geschützführer and also destroyed 1 tank in close range combat.
Lt.d.R. Günter Detjen, he's still listed with Pz.Jg.Abt. 30 as the Ordonanz-Offizier in April 1944.
