Snautzer to your #234:
The photo is Poland September 1939, the unit Heeres-Nachr.Abt. 53 which belonged to XIII. Armeekorps [
http://www.lexikon-der-wehrmacht.de/.../XIIIKorps.htm ], and the place is a Storchlandeplatz next to the Korps HQ. In practice, these were just a meadow or farm field that was used by STOL aircraft for courier purposes and for shuttling the Korps Kommandierender General and his staff back and forth to meetings and on inspection trips. Strictly Army - no Luftwaffe involved.
