Hi,
The top photos were actually taken during the 1930s. After Hitler came to power the compulsory military service was reintroduced. Part of the 'tradition' was to take some entertaining photos to show the homefront that the army was all harmless fun (until they invaded Poland, anyway). So part propaganda, part reassurance of the spouse.
I also have some photos of my military service days on which we pose in a less than professional manner
As you can see I had mastered the use of the Uzi completely. Damn, we were young back then
