Since September 11, 2001, America’s military has faced a new type of warfare. Stealthy warriors stalk a shadowy enemy and advanced technology strikes from afar. The royalty of the 20th-century battlefield — armor and artillery — are virtually absent. Adjusting to this new reality has brought changes in strategy, tactics, programs and budgets. And each change will alter the lives of the men and women of the Army, Navy, Air Force and Marine Corps. On the one-year anniversary of the attacks, Stars and Stripes examines this transformation in “Target: Terrorism.”

Marine Corps adapted to challenges, ever-changing needs of war on terror

Navy undertook its traditional missions, along with new kind of battle

In the vigilant Air Force, they now ’wake up to war every morning’
