Factual errors: There are numerous errors in Sir's uniform.
Continuity: When cadets Kelly and Carla walk to Kelly's house to pick out dresses for the dance, they are wearing bags across their shoulders. As they enter the house, the bags are gone.
Continuity: When Kelly does her impromptu routine with Jennifer on the field, her rifle disappears.
Continuity: When Major Rigby picks up Kelly's dropped rifle, it is pointing in a different direction than when she dropped it a second before.
Errors made by characters (possibly deliberate errors by the filmmakers): Sir calls Brad "Cadet Captain Rigby", instead of Cadet Major Rigby when telling Kelly she made the drill team.
Continuity: When Kelly drops the rope down to save her dad, it is clearly long enough. Then it's too short, then in the next shot the rope is long again.
Factual errors: Girls at the school are wearing blue cords. The blue cord is an honor given only to members of the Infantry, a solely male MOS.
Audio/visual unsynchronized: When at Kelly's trial, Carla says "It's just paint", when you can tell she says something else.
Factual errors: When Cadet Kelly is sentenced to the drill team, her rank on her shoulders of her jacket (which should be PFC and look like Carla's rank) is not visible. She has no rank there. Though she has the rank insignia on her shirt.
Factual errors: The Cadet's Class A uniform trousers are bloused (cuffs tucked into the boots). This is not authorized wear of the uniform unless part of an active airborne unit.
