Plot hole: Chandler chooses Granderson as his XO over Cameron Burk, partly because Burk made an error of judgement and partly as Granderson has been with him since the beginning. However, he completely overlooks the navigator, Lt Mejia, who is a highly competent officer who has also been with him since the beginning and has considerable seniority over Granderson (but is a recurring character as opposed to being on the main cast). While much is made of Burk being demoted, nobody says a word about Mejia being passed over.
Factual error: They have EOTech or similar holographic sights mounted on their rifles, but "scope in" with a night vision sniper rifle scope of some kind to take out the two targets. The EOTech holographic sights are not night vision, nor have the magnification and reticle that was used in the show.
