A very good series done by PBS in 1989. A panel of experts deal with a hypothetical situation from recruiting a soldier to going into combat and treatment of prisoners and torture.

Resource: Ethics in America
Part I Description:
How do we wage war when the enemy dresses as civilians and children throw bombs? Generals William Westmoreland, David Jones, and Brent Scowcroft, correspondents Peter Jennings and Mike Wallace, and others question the duty to follow orders and a commander's obligation to protect soldiers.

Part II Description
The carnage of My Lai raises the issue of confidentiality between the soldier, his religious confessor, and military justice. Generals debate the clash between military tribunals and the right of confidentiality with Chaplain Timothy Tatum of the U.S. Army War College, the Reverend J. Bryan Hehir of the U.S. Catholic Conference, and others.
