Common Sense Note
Parents need to know that violence and death in this war drama includes gunfire casualties at close range (with blood), a helicopter crash, and a car wreck -- the latter actually being a suicide. One character is a drug addict, and the hero has a drinking problem (but seems to kick the habit). Swearing is R-level, with the f-bomb and the c-bomb dropped on a few significant occasions, and there's one use of an anti-Arab slur. The script is not exactly anti-military, but lethally mutinous actions happen, and undercurrents persist of generals and Pentagon spin doctors covering up and suppressing the truth.
One off-color reference about "humping cheerleaders." Hunky guys in a locker room.
Battlefield violence includes characters set on fire and shot at close range and bleeding. There is a spectacular, explosive suicide via car-train collision.
The s-word, the f-word, "ass," "Jesus Christ," the c-word (as pertaining to females), the racist slur "ragheads."
The military setting brings out themes of the slippery nature of "truth" in battle heroics and taking responsibility for one's actions -- even in a desperate situation under dangerous enemy fire. Along with it is the idea of sacrifice, bereaved families, and under-the-radar grief in war causalities (the hero snubs a Presidential ceremony to instead privately comfort a lost soldier's grieving relatives).
The hero uses Apple laptops.
Drugs / Tobacco /
Characters smoke. Serling drinks to steady his nerves after combat flashbacks and is accused/blackmailed about being an alcoholic. Soldiers in a VA hospital take pills and IV medication, sometimes to excess. One character confesses to being an IV drug abuser (which may or may not have been a consequence of war trauma).
