The military is expanding its authority and reach along swaths of the southern U.S. border where troops have been empowered to detain people who enter the country illegally.
Designated militarized zones will soon cover nearly one-third of the U.S. border with Mexico under supervision of nearby military bases. Federal prosecutors have filed criminal trespassing charges in the militarized terrain against more than 1,400 people, adding to possible consequences for people who cross the border illegally.
