Other mistake: Both Brenner and Sunhill are First Sergeants, yet their military IDs are very different: Brenner's is just a plastic ID card, but Sunhill has both a police ID badge as well as a paper card authorizing her to make arrests.
Suggested correction: Paul Brenner is a Chief Warrant Officer 4, Sarah Sunhill is a Chief Warrant Officer 2. His mil ID is 1SG because he is undercover, it's not Paul Brenner's. First Sergeants are never CID agents, though Master Sergeants could be. Brenner holds his CID credentials to the MP's at the gate when heading to the murder scene.
