The Pentagon says it has a well planned schedule to improve the armor of military vehicles in Iraq.

In a briefing Thursday, Lieutenant General Steven Whitcomb said the military had enough resources and was installing additional armor on military vehicles already in Iraq and Kuwait. 

He acknowledged, however, the increased armor would not protect troops from improvised explosive devices detonated from underneath the vehicles. 

General Whitcomb stressed that increasing the armor on vehicles is just one part of the Army's strategy to protect troops.  He said a high priority is finding and stopping the insurgents from building the explosive devices.

The briefing comes one day after Defense Secretary Donald Rumsfeld, visiting troops in Kuwait, was asked by servicemembers why their vehicles were not adequately protected.
