Military Presence at U.S.-Mexico Border Raises Concerns for Migrants and Environment
The deployment of military forces to the U.S.-Mexico border has stirred a mix of support and concern among Arizona communities. While some local officials have expressed approval, others warn of potential dangers to migrants and ecological impacts.
President Donald Trump’s directive to position military units along the border has been welcomed by certain Arizona officials. They believe it will enhance border security, but critics argue that it may drive migrants towards more perilous crossing routes and harm the environment, which is home to numerous endangered species.
James Holeman, founder of Battalion Search and Rescue, commented on the risks involved, stating, “Militarizing the border has historically only ramped up deaths.” His organization conducts searches in Arizona and New Mexico’s remote areas for migrants who succumb to the harsh desert conditions.
On April 11, Trump issued an order for the military to assume control of the Roosevelt Reservation, a strip of federal land extending from the Pacific Ocean to New Mexico, bypassing the 1878 Posse Comitatus Act that restricts military engagement in civilian law enforcement. Migrants entering this zone could face military detention for trespassing.
This military strategy encompasses most of Arizona’s border counties—Yuma, Pima, Santa Cruz, and Cochise—excluding a 62-mile area in Pima County managed by the Tohono O’Odham Nation. The tribe’s ancestral territory straddles the border, with about 2,000 of its 34,000 members residing in Mexico.
Even before the military was deployed, the Tohono O’Odham reservation was a hotspot for illegal crossings due to its flat terrain and minimal barriers. The tribe opposed constructing a border wall during Trump’s initial term, leading to gaps that could become more attractive for smuggling activities.
With military reinforcement, the number of troops at the border has increased from 2,500 to 10,281, according to U.S. Northern Command figures. Cochise County Supervisor Frank Antenori expressed support, stating, “It’s about time the federal government got serious about securing the border and protecting the citizens of this county.”
Conversely, Pima County Sheriff Chris Nanos highlighted concerns about the potential deterrent effect on migrants needing assistance. He advocates for immigration reform that simplifies the path to citizenship rather than increased militarization.
Environmentalists are worried about the potential impact on the Sonoran Desert’s ecology, including 23 endangered species. Secretary of the Interior Doug Burgum, however, claims that the military’s presence will preserve delicate habitats, though critics like Russ McSpadden from the Coalition for Sonoran Desert Protection argue that previous wall constructions have already caused significant ecological damage.
Despite a significant decrease in illegal crossings since Trump took office, the enhanced military presence aims to further strengthen border security. However, groups like Battalion Search and Rescue continue to find evidence of the hazards faced by migrants, particularly those taking the dangerous “poor man’s route” through the Organ Pipe Cactus National Monument.
