U.S. Air Force Senior Airman Tyler Dudley, a security forces response member with the 509th Security Forces Squadron, guards a U.S. Air Force B-2 Spirit bomber at Royal Australian Air Force Base Tindal, Australia, March 22, 2016, while aircrews conduct an engine running crew change. The B-2 was one of three that were deployed to the Indo-Asia-Pacific region from March 8 through 29 to enhance bomber crew readiness and proficiency and to integrate capabilities with key regional partners. U.S. Strategic Command bombers regularly rotate through the Indo-Asia-Pacific region to conduct theater security cooperation engagements with U.S. allies and partners and demonstrate a shared commitment to promoting security and stability in the region.
