Channel Ten, 8.30pm

This third-season episode is all about the American way. NCIS agent and former navy SEAL Sam Hanna (rapper LL Cool J) gets to say the line, ''It's what we do,'' almost continuously throughout the investigation into the discovery of a stiff during a military exercise. In a nod to the original, the resident mature-age actor here is Linda Hunt (who has played the kooky old bird in everything from Kindergarten Cop to The Practice), as diminutive unit matriarch Hetty Lange.
