Stop Fooling Around... Soldier! (1977)

Four young French conscripts are doing their military service in Germany. They feel far from France, and the barracks look like a prison to them, especially since evening outings in German garrison towns are not particularly fun. But these four conscripts of the contingent are not lacking in imagination to set the mood in the barracks, especially with the help of charming young German women who are attracted by the little French.
