Goofs

After servers power down during final battle and the three protagonists are arrested, they magically appear powered up again in the background of a closeup shot of Max.

(at around 1h 03 mins) When Max and John are talking (after the scene when they met in Moscow) the time on the clock in the back keeps on changing. Its 1100 in the start, then switches between 1045, 1500, 1830 and 1100.

During the scene where echelon is upgrading itself, Raymond Burke's suit and tie changes from gray with a striped tie to brown with a polka-dotted tie and then back again.

During the car chase, max is sitting in the yellow minivan. The right rear light is damaged but is fixed again during the chase.

When Peterson sits down at the blackjack table, a shot from the dealer's perspective shows a couple walking behind him. After his big bet, there is another shot from the dealer's perspective and the same couple walks behind him again.

When Max and Reed are being chased, the yellow van they use doesn't have rear windows. Yet, when Reed is going to reverse and hit Grant's car, they look back as if there were windows.

The rifles carried by the S.W.A.T. team in Omaha are made to look like AR15s, but are actually modified AK 47s with extra pieces attached such as a fake receiver cover above the real one to attach the carry handle and the butt stock. At least one of the team members is carrying one with his finger on the trigger, but you can see the hammer resting on the rear of the bolt through the gap in the side (uncocked), which means that pulling the trigger would do nothing without racking the bolt.

When Agent Grant, John Reed, and Max Peterson are looking at the Property Search Page for "the Omaha Facility", the word "hangar" is misspelled. It is spelled "hanger" with a letter "e". As a shed, building, or storage unit, it must be spelled as "hangar" with a letter "a".

The airplane crash news footage doesn't happen in Bangkok, Thailand. The plane actually crashed in Indonesia. There's a yellow police line in Indonesian language ("dilarang melintas garis polisi") that is only used by Indonesian police.

Coordinates shown with NSA Headquarters (N38 57.122 W77 25.887) actually belong to Dulles Airport.

There are no mountains near Omaha.

The hangar in Omaha is surrounded by an apron built using hexagonal tiles used in construction of Warsaw Pact military airfields.

In the end, Max discusses with Reed that no charges are pressed against him, yet he has been bailed out by Kamilla, which would not be necessary as he is a free man.
