While rife with inaccuracies in all things dealing with the events which a light infantry squad faces in wartime, it has pretty much stayed nonpolitical. There is one character that somewhat voices a contrary view, but even so, it is through the eyes of a young man who is an idealist and is somewhat overwhelmed by the events surrounding him.
The sergeant in charge of the squad on which the series centers is portrayed as somewhat disgruntled at having had his tour extended by does not shirk away from doing his mission. While he is a bit of a firebreathing, kick-your-soldiers-in-the-ass NCO, he does care about his soldiers and gets irate when they do something stupid. The second episode in which they were manning a roadblock and his soldiers would not stay away from a shot up car brought this out. It seemed that at every moment he had to keep ordering his young troops away from the car because their curiosity kept gettting the best of them. It brought back a memory or two of my own dealings with knuckleheaded, curious privates.
While as far a good portrayal of proper military procedure it is a disaster ("Tour of Duty" was dozens of times better technically), "Over There" has not been critical of the war. Even the interegation episode did not show an Iraqi prisoner being trully abused, mostly just "vigorously" interogated. The show is not as left leaning as I had thought it would be.
