In the penultimate scene of series 3, Jack Ryan wears a 'cutaway' collar shirt when going in to receive his medal of honor. In the final scene, he's walking out of the building wearing a completely different collared shirt.
During the scene panning across the Blackhawk approaching the USS Roosevelt, the right seat pilot's hand is shown and it's white. When communicating with the USS Roosevelt the pilot in the front right seat is black.
When the Blackhawk departs, the writing on the tailboom is reversed.
