A National Defense Area has been established along the Yuma border.

The National Defense Area is adjacent to the Barry M.Goldwater Range and the Cabeza Prieta Wildlife Refuge along the International Border east of Yuma. The established zone will allow U.S.military personnel to temporarily detain people who unlawfully enter the restricted area. Temporary detainees will then be turned over to U. S. Border Patrol agents. Those detained could face charges for violating defense property, entering military property, and additional charges of illegal entry. Other National Defense Areas have been established along the border in Texas and New Mexico.
