The personnel selected for ESU become highly trained, elite members of the NYPD who perform rescue, SWAT and other high risk tactical, counter-narcotic and counter-terror operations.
There are minimum time-in-grade requirements before an NYPD officer can apply to transfer to ESU. Police Officers must have a minimum of 5 years on the job with a minimum annual rating of 3.5. Supervisors in the rank of sergeants and lieutenants must have 2 years in rank before being assigned to ESU. In addition, all ESU candidates must be approved by a group of current ESU members to ensure that they will integrate into the unit successfully.
