Bowery Battalion

The gang mistakes a practice air raid for the real thing. They immediately sign up for the military. Slip tries to stop them but gets trapped himself. The boys get into constant trouble at camp but end up rescuing Louie and saving a secret weapon from foreign spies.

This was released soon after the start of the Korean War. I doubt it's anything deliberate. This is not wartime patriotism but rather a random coincidence. "At ease" is a funny button to a comedy scene. The spy stuff is very convoluted but that could work in a screwball comedy. I would leave Louie out of this one or at least interrogate him into the story in a more simple way. All in all, this is ok for Bowery completist.
