While city residents and visitors of Las Vegas celebrated New Year's Eve, more than 140 Nevada National Guardsmen were participating in Operation Vigilant Sentinel, a real-life exercise which had Guardsmen watching over spots in the city, manning traffic control points, and patrolling at McCarran Airport. This is the 11th consecutive year the Nevada Guard has trained during the holiday. Story by Sgt. Victor Joecks. Hosted by Tech. Sgt. Amber Monio.
