As a former Marine who was deployed to the same place at the same time, I think this show did an excellent job of capturing the 'essence' of what the invasion of Iraq was like to the men who were there. This show comes closer to accurately portraying wartime Marines than any other show I've ever seen. I think this is as close as Hollywood can get short of being there and filming it live. Sometimes the special effects are a little over the top, but the dress, demeanor and dialog of the characters are very accurate.
The attitudes, bearing, and language of the Marines portrayed are spot on, as well as the day to day problems and trials they encounter. I guess what I really like about this show is the lack of cheesy moto propaganda. The films are light on pro- or anti- war propaganda and heavy on truth. I'm sure some people think that the 'get some' attitude of the Marines glorifies the war while others think that pulling no punches in the collateral damage department is anti-war, but that isn't the case. These films boldly show the invasion of Iraq for what it was, for better or worse. The Marines have 'get some' attitudes in this show because Marines really have that attitude. Collateral damage, chaos and confusion among U.S. forces are in the show because it really happens in warfighting.
