Continuity mistake: When Hunt and Walker extract Lane from an armoured convoy by alternate means, right after they push the truck containing Lane into the water, one of the police in the convoy tries to shoot Hunt and Walker, leaving 3 bullet holes in the front windshield of the truck.

The most obvious occurrence when the bullet holes disappear is when Hunt and Walker kick the front windshield of the truck to flee with a motorcycle after it gets stuck between buildings.
Continuity mistake: When Ethan is chasing Walker up the brick tower, the hatch to the roof is in the middle of the tower when seen from the inside.
