Pentagon orders review after Fort Hood rampage

The probe will be led by former US Army secretary, Togo West, and former chief of naval operations, Admiral Vern Clark.

US Defense Secretary Robert Gates on Thursday announced a major review of the Fort Hood shootings to examine if the military had missed warning signs or remained "vulnerable" to similar assaults.

The 45-day review would look at possible "lapses or problems" before this month's army base shooting that killed 13 people and "what can we do to prevent something like this from happening again," Gates told a news conference.

- We do not enter this process with any preconceived notions - he said.

- However, it is prudent to determine immediately whether there are internal weaknesses or procedural shortcomings in the department that could make us vulnerable in the future. -

The probe will be led by former US Army secretary, Togo West, and former chief of naval operations, Admiral Vern Clark.

An army psychiatrist, Major Nidal Hasan, has been charged with the murder of 13 people in the November 5 rampage at Fort Hood in Texas, in which 42 people were also wounded.
