Set in Iraq, the FX combat drama “Over There” (9 p.m., FX) completes its first tour of duty. In the season-ender, the fire team protects a civilian convoy on a road that has seen frequent clashes with insurgents. As the situation grows more dangerous and intense, the squad members begin to doubt the judgment and competence of their superiors. Elsewhere, Bo gets a break in his attempts to rejoin the Army and Sergio gets unexpected news from Anna.

Despite its attempts to amplify and comment on contemporary events, and the expansion of the storyline to include home-front melodramas, “Over There” always seemed to be an update of the old “Combat” series. Like “Over There,” it used battlefield situations to showcase superb ensemble acting. Only I’m still not sure if anyone has emerged as the clear star of “Over There” to match the presence of “Combat”‘s Vic Morrow. In a strange twist of fate, Morrow would die during the filming of a combat sequence during the making of “Twilight Zone: The Movie.” The late actor is the father of accomplished actress Jennifer Jason Leigh.

As “Over There” completes its first season, it faces a major distraction. Steven Bochco is not only the producer of “Over There,” he has his name in the official title of the show. ABC has recently recruited Bochco to run the hit series “Commander in Chief,” starring Geena Davis as the first female president of the United States.
