The Private Snafu films were clearly made to be seen by soldiers and not by the general public. The dirty jokes, sexual innuendos and language is relatively tame today but never would have been allowed in the regular theaters due to the Production Code. But, such off-color remarks went over very well with the enlisted men and helped to illustrate important information in a humorous and memorable fashion.
According to IMDb, this short was never released to the servicemen because apparently a section talking about some "super-bomb" was considered to be too close to the secret atomic bomb that the country was working on at the time. However, today you can see and enjoy it.
Snafu comes home for a visit and as usual, he's a total idiot--and very reminiscent of his other film, SPIES. He talks and talks and accidentally gives out vital information concerning his unit...and naturally the enemy is able to use this against us. Clever, yes, but also not quite as crazy and funny as the usual Snafu film.
