Good Kill goofs

While preparing for a strike on an Al-Qaeda target in Yemen, crew member Suarez asks, "Since when are we at war with Yemen?" Her superiors at CIA headquarters reply that ""we are dealing with sub-state actors."" Although the expression exists, it is not typically used about terrorist organisations; such groups are properly described as non-state actors, and an officer issuing orders from Langley would not confuse the two terms.

The Air Combat Command patch worn on the flight suits is incorrect. The genuine patch has the blue field at the top and the red field at the bottom. Also, the sword on the genuine patch points downwards.

When Ethan Hawke exits Creech AFB he makes a right-hand turn, heading northwest towards Las Vegas; in reality, when leaving Creech AFB the correct manoeuvre is a left-hand turn, towards the southeast.

In one scene, Major Egan says he relishes the adrenaline of flying combat missions, including the terror and risk of attempting a night-time landing on the pitching deck of an aircraft carrier. However, Major Egan is portrayed as serving in the Air Force, whose pilots do not operate from carriers — that role belongs to Navy or Marine aviators — and the aeroplane he flies, the F-16 Fighting Falcon, is not built to land on aircraft carriers.

At the funeral of a Taliban commander, the men were arranged in an L-shape. According to Islamic practice, they should stand in rows behind the imam, with the deceased placed in front of them, and everyone facing Mecca.

By the film's end Suarez says "I turned in my wings", signalling she has resigned from the Air Force, so the rules forbidding fraternisation between officers and enlisted personnel would no longer govern her relationship with Egan. Enlisted personnel do not have the option to resign from the United States armed forces; officers may do so in certain circumstances. Enlisted members can opt not to re-enlist when their current term of service expires, but they cannot simply walk away.

Egan claims he took his wife up in his F-16 on their first date. Most F‑16s are single-seaters; there are a few two-seater versions (senior officers typically fly with a second pilot), but civilians very rarely get the opportunity to fly in an F‑16 — such flights are normally reserved for members of Congress, VIPs or selected press, never girlfriends or spouses.

At the end of the film, when Airman First Class Suarez is pictured in her Air Force blues, she is seen wearing, among other items, the Air Force Good Conduct ribbon — an award normally presented to enlisted personnel after three years of service. However, enlisted airmen are typically promoted to Senior Airman at that three-year milestone, so her depiction as an Airman First Class indicates she would not yet have been eligible for the Good Conduct Medal at that rank.
