Visible crew/equipment: When Shane is in the car with Zoe, he yells "Go!" and the car takes off past the camera. If you look very carefully as the car moves past the camera, you can see the camera reflected in the car window very clearly. (01:02:05)
Other mistake: When Shane is installing the security cam, he looks to verify the image, but we are shown a standard quality image that you would find in a typical security cam. If he was on a top priority project for the military, the video quality would be way above what we see. It would also most likely not look like an off the shelf video camera (i.e. it would likely be less detectable than what he put up).
Visible crew/equipment: When Shane and the kids are going home you can see a camera's shadow on the van.
Other mistake: The mom comes home and finds the Sound Of Music poster for the performance that her son is in. Louisa on the poster is a completely different actress from the one in the rehearsal scenes.
Continuity mistake: At the beginning of the film Vin Diesel is shot, presumably in the chest or torso, but in the shirtless scene during the Girl Scout troop meeting he doesn't have a single scar. (00:06:05 - 00:36:20)
Other mistake: When Shane is in his officer Navy uniform in the hospital, after his release from being shot, you will notice the belt buckle is centered incorrectly. A for effort, F for wrong way. Any military uniform, the belt buckle is centered off of the zipper flap - to the left, but in the movie it is centered off to the right. Another military uniform mistake. Someday these movie makers will get it right.
Answer: He is telling a story of one of his missions and just changes soldier to elf.
