Fort Hood, the site of Thursday's horrific attack on U.S. soldiers, was the focus of a NOW on PBS report about American troops suffering from post-traumatic stress disorder.

Many of the thousands of U.S. troops discharged from the Army each year suffer from PTSD and say they lack the vital care they need. The Army claimed these soldiers were let go due to pre-existing mental illnesses or because they were guilty of misconduct. But advocates argue this was a way for the Army to get rid of "problem" soldiers quickly, without giving them the treatment and benefits to which they're entitled.

In our online coverage, NOW interviewed two Fort Hood soldiers about the personal trauma they experienced while fighting in Iraq.

NOW will air a new report about caring for injured veterans, including those suffering from PTSD, on November 20.

On Thursday, the Senate passed legislation that will provide monthly stipends and medical benefits to family members who stay home to care for severely injured veterans of the wars in Iraq and Afghanistan.

The Senate’s bill also includes training for the caregivers, money to cover their travel, and nearly $1 billion for veterans’ medical facilities. The House has passed similar legislation and the next step is for a meeting of a House-Senate conference committee to resolve differences between the two bills.

This Friday on NOW (check local listings), we visit families caring for wounded vets who have suffered traumatic brain injuries, many of which require round-the-clock attention. The Pentagon estimates that as many as one in five American soldiers are coming home from war zones with traumatic brain injuries.

According to ABC News, two of the masterminds behind the attempt by Umar Farouk Abdulmutallab to bring down Northwest Flight 253 on Christmas day were former Guantanamo Bay detainees freed in 2007 who then attended a terror rehabilitation program in Saudi Arabia.

After being released from the program, the former prisoners are believed to have moved to Yemen where they joined al Qaeda as military commanders.

"The so-called rehabilitation programs are a joke," a U.S. diplomat said in describing the Saudi efforts with released Guantanamo detainees.

The controversial Saudi program attempts to rehabilitate terrorists and integrate them back into everyday life through a combination of religious, psychological and social programs. NOW on PBS traveled to Saudi Arabia earlier this year for an inside, in-depth look at the controversial initiative.
