The current unit consists of 15 Native American Patrol Officers representing nine Native American tribes (Tohono O'odham, Navajo, Kiowa, Sioux, Blackfeet, Yurok, Omaha, Yaqui, and Pima) who employ traditional tracking skills combined with modern law enforcement technology to enforce immigration and customs laws on the 76 miles stretch of land the Tohono O'odham Nation shares with Mexico.
