Show of the week: Frontline: The Wounded Platoon

Since the Iraq war began, 36 soldiers at Colorado’s Fort Carson have committed suicide, and 14 have been charged with or convicted of murder—three of those from the same platoon. Frontline follows the Third Platoon, Charlie Company, 1st Battalion of the 506th Infantry, from heroism and horror in Iraq to depression and drug abuse at home—throwing a harsh light on the war’s high human cost, and exploring military and civilian authorities’ failure to provide compassion to traumatized veterans.
