At the beginning of the first course, it is stated "12 minutes or less" is what is need to pass that part of the training. Yet Cortez finishes in 13:10, and Jordan finishes after him. Even with a 30 second deduction for all females in training, that still doesn't put her under the 12 minutes she needs to pass the course.

At the bar after SERE training, O'Neill has a white butterfly stitch over her right eye. In the next shot, it's gone and replaced with standard stitches.

Near the end, when the helicopters are flying in to support the soldiers, it is possible to see in at least one shot that the Cobra helicopter's rocket pods are empty (the sun shines through the tubes from the back). Later, the same Cobra is shown firing its rockets, even though this would not be possible.

When the submarine on which the SEALs sail dives, it is shown as an Ohio class missile sub. When it is submerged, it turns into some other sub. Before the team surfaces, it has switched back to an Ohio.

When the first trainees are jumping out of the helicopter into the water for the S.E.R.E. training course, the sun is shown just rising over the horizon. However, the shadow cast by the helicopter's tail (viewed from inside the helicopter) indicates that the sun is instantly much higher.

Troops on patrol would not use their names over the radio. They would all have call-signs, usually numerical as in 5-5-B, to denote who the were so any enemy interception of their signals would not give away personal information. (Pronounced five - five - bravo)

At several points throughout the film, the SEAL instructors commit blatant assaults on the trainees, to include beating O'Neill so badly that she has visible injuries on her face, as well as repeatedly striking an injured officer on his wounded knee in order to make him drop out of training. Even within the rigors of SEAL training, these acts would be completely illegal and would probably result in the perpetrators facing felony court martial charges.

When LT O'Neill is in Washington, her collar insignia is incorrectly placed on her khaki blouse according to Navy regulations.

In the film, the submarine's commanding officer briefs the SEAL trainees on their upcoming mission. This would not happen in a real situation. The captain's job is to command the ship (or boat, as submarines are properly called); briefing any combat team would be done by someone else, possibly an intelligence officer.

Early in the training, O'Neill (and presumably the other trainees) is blindfolded and lying on a table while having water poured into her mouth and on her face. In the film it's referred to as drown-proofing, when in actuality this is very close to how waterboarding is done during the Navy's SERE (Survival, Evasion, Resistance, Escape) training. SEAL drown-proofing takes place in a swimming pool.

The trainees are part of a Combined Reconnaissance Team (CRT); hence, the training is not identical to Navy SEAL training, as it combines elements from all the branches.

In the tub scene, O'Neill says she's survived Jump School and Dive School. However, there are no Jump or Dive pins on her uniform.

At the end of the S.E.R.E. scene, the Master Chief passes Instructor Johns a bottle of liquor. Johns takes a sip out of frame, but when the bottle enters the frame, the cap is still screwed on.

In the briefing for the Libya landing, the coast is shown as southern (sea south of the land). Libya has no southern coast, the entire country lying South of the Med. The maps could conceivably have been drawn "South up" but this is against all military (and geographical) convention and unlikely in the extreme.

At approximately 28 minutes into the film a medical corps officer tending to the trainees is referred to as "corpsman"when dismissed. "Corpsman" is an enlisted rating.

Several times throughout the film, enlisted instructors and trainees refer to LT O'Neill by her last name. In reality, she would have been referred to as Lieutenant or Lieutenant O'Neil. Military courtesies exist even in a training environment.

When O'Neill exits the Hummer upon arriving at base, she closes the door behind her, but the door does not latch. It can be seen swinging back open just as the vehicle leaves the camera's view.
