Factual error: In the hearing, Harp said he completed his basic training 3 years ago at Parris Island. Harp is in the Air Force, and Parris Island is a boot camp for Marines. (00:07:43)
Factual error: The Captain fires his Glock and it's dry. Firstly once a Glock's magazine is depleted the slide is held back by the empty magazine and slide stop. Secondly he pressed the trigger twice and the gun made a clicking noise twice. Glocks are striker fired, when it's empty the trigger can only be pressed once and after that the trigger stays to the rear unless the slide is racked or a new magazine is inserted and the slide is racked or slide stop is depressed. (01:00:18 - 01:01:00)
Other mistake: In the scene with Harp facing the hostage takers between the 2 trucks full of GUMPs, Harp's rifle has no trigger. (01:04:00)
Factual error: Lt. Harp is told by Capt. Leo that the Lieutenant has 56,000h of UAV flying time, That is ridiculous. Even seasoned pilots of the Military Airlift Command do not have that many hours. Drone pilots can fly up to 1,800 hours a year, and Harp hasn't been flying drones for 31 years straight.
Factual error: Numerous military-related flaws - incorrect military protocols (officers in formation with enlisted personnel), marching orders (the leader commands double time, but nobody runs), and unreturned salutes.
Factual error: CPT Leo tells Harp he just flew 10,000 to get there. This war is in Europe. Even assuming the easternmost area, say Poland, Nevada is only 5,700 miles away.
Factual error: LT Harp is talking with CPT Leo. Leo, reciting Harp's achievements, says he has 56,000 hours of flying drones. Impossible. A Lieutenant, say a First Lieutenant, would be promoted to Captain in typically four years. 56,000 hours in four years is 4,667 a month. It should be divided by eleven, as he is entitled to one month leave. So the corrected amount is 5,091 hours a month. This is 254.55 hours per workday! Yeah, right.
Factual error: At his hearing, a drone pilot (a lieutenant) is asked where he did his basic training. He replied, "Parris Island." Wrong. US Air Force officers do not go to Parris Island. Some, such as ROTC and Academy graduates, do not go to basic training at all. Others go to Officer Training School. Parris is a Marine Corps base that gives basic training to enlisted Marine Corps personnel.
Character mistake: The woman with the AK-47 doesn't have the covers on the red dot optic open. In other words, she can't see her target.
