NEW YORK-- New York Army National Guard Sgt. Leopoldo DeSilva (left) pulls security duty in Pennsylvania Station on Wednesday, May 2 with an Amtrack Police Officer. The Soldiers are members of the New York National Guard’s Joint Task Force Empire Shield which provides security augmentation to law enforcement agencies at transportation hubs in the New York metro area. The team was part of a Multi-Agency Super Surge (MASS) in which police saturate key transportation nodes to deter attacks. The May 2 MASS was the 100th time the New York National Guard supported that kind of security operation.
