The items that a soldier was issued are listed in the Soldbuch. Generally speaking, basic clothing and equipment items are recorded on pages 6 and 7 and special equipment such as weapons and gas protection equipment are recorded on pages 8a-8d.
Scans of Soldbücher for nearly any unit (or at least unit type) can be readily found online, including on this very web site. If you can read these words, you can find this documentation online. There is no need to speculate about what a soldier was issued, what kind of boots he might have had or how many of each item, etc. The documentation for this is readily available and may be surprising as it often contradicts reenactor myth. The Soldbuch will not list what exact model of tunic or field cap was issued but educated guesses can be made based on other extant documentation.
One of the units that we portray for living history is Sicherungs-Regiment 195. An entry in a Soldbuch from this Regiment shows the following issue of basic clothing and equipment on pages 6-7, dated June 1943:
1 helmet
1 field cap
1 field blouse
1 sweater
1 pair of trousers
2 collar binds
2 pairs of underwear
2 shirts
3 pairs of socks
2 pairs of low boots
1 clothing bag
3 greatcoat straps
2 ammunition pouches
1 ID disk
2 hand towels
3 handkerchiefs
1 folding fork/spoon
1 pair suspenders
1 wool blanket
1 pair of gloves
1 toque
1 sewing bag
2 mess kit accessories (illegible)
1 greatcoat
1 Tornister
1 mess kit
1 Zeltbahn with accessories
1 belt
1 bread bag with strap
1 canteen
1 HBT uniform
1 pair gaiters
This photo shows this full scale of issue (minus the illegible entry). I’m not sure what an issue sewing bag might have looked like so I included a private purchase type “Kameradenhilfe” sewing kit. The relevant Soldbuch pages are also shown. This soldier also had a gas mask, and a French rifle and bayonet, recorded on pages 8a-8d. He had a Soldbuch too, of course, which is the source for this information.
