Discipline Pays Off (1951, 10:42) is another UPA training film for the US Navy. Though it offers more enjoyment and production value than Swab Your Choppers, this look at regulations throughout the ages still doesn’t have the charm of the earlier entries in this collection. That it was originally intended and budgeted just for those in the marine services and not for viewing by the general public is a reason for its concentration on factuality, of course, but it still takes its time to make a point.
