ORT MONROE, Va., Sept. 4 — The Army is looking to instill the fighting spirit in some unlikely combatants — its cooks, mechanics and other support troops who are normally far from the front lines.

Unlike the Marine Corps, whose credo is that every marine is first and foremost a rifleman, the Army has too many soldiers who have lost touch with their inner warrior, said Gen. Kevin P. Byrnes, the Army's top training general.

And, he said, it is time the Army borrowed a lesson from the Marines.

"We've become too specialized," said General Byrnes, the head of Training and Doctrine Command here. "Ask a junior enlisted who they are, and they'll tell you, `I'm a mechanic,' not I'm a soldier. We need to change that culturally in the Army."

So beginning next year for soldiers and in three years for officers, the Army plans to formally inculcate what it calls a "warrior ethos" throughout the ranks.

Army officials are not worried about the battle-readiness of their front-line fighting ranks, like infantry and armor troops. But for support troops, many of whom rarely handle a weapon or drill for combat after basic training, the strategy will probably mean more marksmanship practice, tougher physical training and, for officers, more small-unit leadership skills in the field.

The issue of instilling a combat mindset in troops working behind the lines has taken on added resonance since the ambush of an Army supply convoy in Iraq in March that resulted in the deaths of 11 Americans and the capture of Pfc. Jessica D. Lynch and six other soldiers.

Although the soldiers had completed basic training, they were mostly cooks, mechanics and other support personnel who had little or no combat experience.

But Army officials here said that emphasizing a warrior mentality throughout the ranks had been under way for 18 months as leaders in the Pentagon designed a force for the future that would be agile as well as lethal, and prepared to fight on a battlefield, like Iraq, without traditional front lines and rear areas.

Under plans General Byrnes discussed with reporters here, freshly commissioned second lieutenants would take a new six-week basic leadership course after receiving their commission. Eighty percent of that leadership training would take place in the field.

Officers would then go on to training in their specialized areas, like infantry, armor or intelligence, as they do now after they receive their commissions.

General Byrnes said four pilot programs had been conducted at Fort Benning, Ga., to test the concept for officers and proved successful enough that the training for new officers Army-wide would begin in early 2006. Similarly, the warrior mindset will be included in enlisted soldiers' nine-week basic training courses and their speciality training after that, beginning next year. Support troops could be tested on marksmanship twice a year, like infantry soldiers, instead of annually, as they are now.

In some ways that new emphasis has started. Training instructors in Aberdeen, Md., recite the individual citations from Medal of Honor recipients to inspire recruits. Officials here said the new credo for all soldiers is "put the mission first, refuse to accept defeat, never quit and never leave behind a fellow American."

Maj. Gen. Raymond D. Barrett Jr., a top aide to General Byrnes, said the change meant that support troops would still have physical training requirements, but they might include going through obstacle courses under stressful conditions simulating a combat setting.

Or a mechanic might pass a final advanced training course by repairing an armored vehicle damaged during a mock ambush at night and under simulated hostile conditions.

"The question is, do they think they feel like a soldier?" General Barrett said. "This would test them as mechanics, but it would also test their perseverance."
