Joint Base Lewis–McChord (JBLM) is a U.S. military installation home to I Corps and 62d Airlift Wing located 9.1 miles (14.6 km) south-southwest of Tacoma, Washington under the jurisdiction of the United States Army Joint Base Headquarters, Joint Base Lewis–McChord. The facility is an amalgamation of the United States Army's Fort Lewis and the United States Air Force's McChord Air Force Base which merged on 1 February 2010 into a Joint Base as a result of Base Realignment and Closure Commission recommendations of 2005.
 

Joint Base Lewis–McChord is a training and mobilization center for all services and is the only Army power projection base west of the Rocky Mountains in the Continental United States. Its geographic location provides rapid access to the deep water ports of Tacoma, Olympia, and Seattle for deploying equipment. The strategic location of the base provides Air Force units with the ability to conduct combat and humanitarian airlift with the C-17 Globemaster III.
