German Soldiers

Corporal Gustav Gromeik! July 20, 1913, Elberfeld near Wuppertal - October 16, 1944, Schirwindt/O-Pr
I can't find much information about him either.
Depending on the source, his last name is given as either Gromeik or Gromeike.
I can't find out whether OG was the last rank he reached.
At the end of May/beginning of June 42, he commanded a tank destroyer group of the 2nd Company, Pioneer Battalion 1, 1st Infantry Division in the Neva bridgehead in the area of ​​Army Group North.
When the enemy (2nd Russian Shock Army) attempted to break into the German positions, the group took out 5 Russian tanks in these battles, destroying one of them himself with a limpet mine and thus contributing to the defensive success.
For the EKII and I he wore the Stumabzeichen (general), Verwundtenabzeichen schwarz, Panzervernichter 4x, RK 19.06.1942
