A drill sergeant picking apart a recruit seems to be a common vignette on military-themed comic postcards of this period. Though, I have to imagine that while the postcards are vivid, they would have been out-shown by the colorful language of the real drill sergeants of past and present. Breaking down the individual and building him back up as part of a team has long constituted the basis for basic American military training.
On this card, we meet Joe, a Private who uses this postcard image to relate his experience to a young lady in Pennsylvania. He is stationed at Hendricks Field in Sebring, Florida, a large air base where bomber crews were trained for service on B-17 Flying Fortresses and B-24 Liberators.

Hello Jean. This may give you some idea what I have to go through as I’m the guy that is that way sometimes. How is school going & when will it be out? Here would be a good place for you to play in the sand. Joe.
