Twentynine Palms Base, is located adjacent to the city of Twentynine Palms in southern San Bernardino County.  Twentynine Palms Base is located within the Morongo Basin and the High Desert region of the Mojave Desert, in Southern California and covers more than 998 square miles, which makes it larger than some small countries. 
The Marine Corps Air Ground Combat Center’s (MCAGCC) two-fold mission is to operate live fire combined arms training that promotes readiness of operating forces and to provide facilities, services, and support, responsive to the needs of tenant commands, marines, sailors and their families.
After switching a few commanding units over the decades and receiving new upgrades from each of them, the base turned out to be the largest training site in the United States of America. At the same time, it is the widest and largest US military base in the world, not to mention about the most advanced, detailed and complete training programs.
