The soldiers will provide support for Customers and Border Patrol agents for about a year, much like the 262nd Engineer Company that returns this fall, the Maine National Guard said. The soldiers will not serve in a law enforcement capacity, said Maj. Carl Lamb, the organization’s public affairs officer.
