The name of the dead Marine in this episode was (Sgt) Larry L. Fuentes, same name as the show's special effects coordinator.
Patrick Labyorteaux (Lt. Bud Roberts, Jr.), crosses over from JAG (1995) to guest star this episode.
When Gibbs is interviewing Lt Roberts they mention the 2 JAG episodes, Ice Queen (2003) and Meltdown (2003), in which the NCIS team was introduced.
Before searching the Marines' lockers, Agent Gibbs quickly slaps on latex gloves. Agent Gibbs misses with the pinky on his left hand and goes through a few shots with the latex pinky dangling.
