Members of Kentucky's Army National Guard have been helping install fencing to prevent illegal immigrant crossings in the Southwest.
Kentucky National Guard spokesman Colonel Phil Miller says 767 members have traveled to the region since July of 2006.
Another 680 members of the Army National Guard are scheduled to deploy to the region from May through at least July.
More than 6,000 National Guard troops from around the country are currently working on the border in New Mexico, Arizona, California and Texas, Miller said. Since the operation started in May, Guard members have assisted Border Patrol officers in making 45,000 arrests and seizing 500 vehicles, 170,000 pounds of marijuana and 3,000 pounds of cocaine, said Michael Friel, a spokesman for U.S. Customs and Border Protection.
