WH (Heer) 'Wehrpaß'. When individuals received their registration notice they were to report to the appropriate recruitment center where they would be issued a 'Wehrpaß', until they were inducted into active duty. From the autumn of 1939, when an individual was inducted into active military service the Wehrpaß was exchanged at the recruitment office for the 'Soldbuch' (Pay Book), which remained in the recipients possession as his official military identification document. The recruitment office would retain the Wehrpass and chronicle the individuals active service record in it. The Wehrpaß belonged to Obergefreiter 'Erich Kaiser', after his service in the 'Reichsarbeitsdienst' he came into active military service on 31 August 1939. He served in several units, from 12 November 1940 he served in the '1./Pz.Jäg.Abt.126' (1. Kompanie Panzerjäger-Abteilung 126). He was trained to use the following weapons: Gewehr 98, MG26(t), MG13, Pak 3,7cm and the MG34. He was promoted two times and ended up being an 'Obergefreiten'. On 7 November 1942 he was awarded with the Ostmedal.

From 22 June 1941 he took part in the campaign on the Eastern front and with his unit he took part in the battles near the border of Lithuania (Grenzkämpfe in Litauen), the crossing of the river Danube (Vorstoß über die Düna), battles near Leningrad (Operationen gegen Leningrad), defensive battles around the Wolchow (Abwehrkämpfe am Wolchow) and more, see photos for more details. Interesting original Wehrpaß!
