Continuity mistake: At the bus station, both MPs are wearing Specialist-5 rank on their uniforms. Later in the movie they seem to have been demoted to Specialist-4.

Factual error: At the graduation, the MP's are wearing the National Defense Service Medal. This is authorized for active duty during times when "national emergency" has been declared during times of conflict. It was awarded for service during the Vietnam war, ending in 1974, and not awarded again until the Gulf War in 1990. To wear it, the women would have had to been in the service in 1974, which would mean they've got at least 6 years of service by the time the movie came out. On their class A uniforms, they aren't wearing any service stripes, meaning they've been in for less than 3 years.
