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.
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.
