At the beginning, Cole is instructed to be in charge of the detainees "right hand" but on the bus when she describes the event, she tells the others that she was in charge of his "left arm".
(at around 1h 35mins) Ali is holding the blade on his neck with the right hand, and in the next take, he is holding it with the left hand.
After they subdue the detainee wh3re Cole is spit on, she was ordered to pay attention to the right arm. As they are escorting the detainee down the hall and she is on the left arm.
There is no Farsi (Persian) speaking detainee in Guantanamo bay detention camp. But, several times detainees talk Farsi.
Corporal Ransdell nor anyone else would customarily be authorized to wear their cover (uniform cap) indoors, as several are seen doing in the film. A solider would only wear his or her cover indoors if the individual was under arms.
Whilst all of the other guards on the cell shift watching the detainees check each and every room, including 109 and 110, Cole noticeably doesn't check those two rooms. This is visible on every rotation, and is so evident it's hard to believe it was overlooked. This is especially clear when the credits roll and the two new guards are shown looking in each cell, including 109 and 110.
When Col. Drummond enters the room, Cole orders "attention on deck". This is Navy terminology and would not be used by a Soldier in the Army.
(at around 1h 00mins), Cole calls the detainee "Hey 361!", but the detainee is known as 471.
