Unidentified Photos #21 (Source: Author's private collection) Kevin Scherrer's comments: I concur with Mr. Southerland - Pioneer Kaserne in Hanau. I lived in Old Argonner Kaserne from 1980-82 - just down the road from Pioneer. This Howitzer is travelling west on Route 8. The mystery photo is compared with a current-day satellite (Goodle Maps) photo of Pioneer, and it confirms a solid match.
