# Shadow Wolves

The "Shadow Wolves" are a Native American tactical patrol unit assigned to Homeland Security Investigations (HSI) in Sells, Arizona located on the Tohono Oʼodham Nation that runs along the Mexico–United States border.
The Shadow Wolves specialize in the interdiction of human and drug smugglers in the Sonoran Desert, utilizing both technology and the traditional tracking methods. In addition to the use of high-tech equipment, the unit relies on tracking techniques such as "cutting for sign", which includes investigating any kind of physical evidence left by smugglers (e.g., footprints, tire tracks, thread, clothing). The Shadow Wolves are the Department of Homeland Security's only Native American tracking unit specifically utilized for targeted interdiction operations.
The unit was established by Congressional mandate in 1974 in response to rampant smuggling occurring through the Tohono O’odham Nation.

## History

The "Shadow Wolves" law enforcement unit was created in 1974 by an Act of Congress, after the U.S. federal government agreed to the Tohono O'odham Nation's demand that the officers have at least one fourth Native American ancestry. The Shadow Wolves became the first federal law enforcement agents allowed to operate on Tohono land.
The unit is congressionally authorized to have as many as 21 members but, as of March, 2007, it consisted of only 15 members. Members of the unit come from nine different tribes, including the Tohono O'odham, Blackfeet, Lakota, Navajo, Omaha, Sioux, and Yaqui.
Originally part of the U.S Customs Service, the Shadow Wolves became part of the Department of Homeland Security in 2003, when the U.S. Customs Service was folded into DHS.
On December 22, 2021, during the 117th Congress, Rep. John Katko (R-NY-24) introduced H.R. 5681, which proposed to broaden the Shadow Wolves' authorities while preserving the important legacy of the unit. The bill became Public Law 117-113 on April 19, 2022. The law provides flexibility to reclassify the Shadow Wolves, current and future, from GS-1801 Tactical Officers to GS-1811 Special Agents.
The Tohono Oʼodham Nation, patrolled by the Shadow Wolves, covers 2,800,000 acres (11,000 km$^2$), including a 76 mile (122 kilometer) stretch of land shared with Mexico. It is mainly made up of small, scattered villages. Between 2010 and 2020, interdiction and investigative efforts the Shadow Wolves have led or participated in have resulted in 437 drug and immigration arrests along with the seizure of over 117,264 pounds of drugs, 45 weapons, 251 vehicles and $847,928 in U.S. currency.

## Global training missions

In addition to tracking smugglers on the U.S. border, the Shadow Wolves have also been asked to train border guards and customs agents in other jurisdictions, including Latvia, Lithuania, Moldova, Estonia, Kazakhstan, and Uzbekistan. The unit was also used in the effort to hunt terrorists along the border of Afghanistan and Pakistan by training regional border guards in Native American ancestral tracking methods.
