The New York City Police Department Emergency Service Unit is an operational element of the New York Police Department trained and equipped to respond to very high-risk situations beyond the capability of regular patrol officers.

History
In 1925 the New York Police Machine-Gun Squad was formed to provide the department a rapid response force of heavily armed police. Its primary purpose was to put-down a serious political insurrection using overwhelming firepower and officers assigned to the squad were equipped with Thompson sub-machine guns. In the 1950s, the Machine-Gun Squad was reformed and renamed the Mobile Security Unit.
