The usual playful nature of Pete Smith's commentary feels restricted here because the movie’s clear intention as propaganda doesn't provide much room for his characteristic humor. Despite this, he still manages to work in some critical and negative remarks about Japan, referencing "Tojo," while illustrating how thorough the US Marine training program is. These courageous and admirable young men are being taught unconventional and unpleasant methods so they can match their opponents—who are skilled in martial arts and fighting with primitive weapons—in kind. The film concludes with a sequence resembling an oath, directed toward both the soldier and his country, concerning his bond with his rifle; however, this feels overly patriotic, even considering the era it was made, and ultimately undermines any potential for lightheartedness that could have been achieved if the movie had leaned more into being a recruitment tool.
