Ready Marine Corps

In the event of an emergency, the Marine Corps Mass Notification System (MCMNS) provides real-time alerts to the Marine Corps community throughout the lifecycle of the incident/crisis or installation closure through three (3) methods:

1. Giant Voice (GV)—A voice announc­ing system using exterior speakers, commonly termed “Giant Voice,” that provides real-time information or instructions to most outdoor areas. 
2. Interior Voice (IV)—Interior speak­ers or sirens in individual buildings that provide real-time information or instruction to building occupants or personnel in the immediate vicinity of a building, including exterior entrances and gathering areas. 
3. Enterprise Mass Notification System (eMNS)—An interactive, com­munity notification system capable of providing voice and/or data messages to multiple, designated receivers through various types of notifications.
   1. Automated response option – Some Mass Notification messages may require an automated response from the Marine, Civilian Marine, or Contractor (e.g. “(#1) Recall acknowledged, will report immediately, (#2) Recall acknowledged, will report in 30 minutes, (#3) Message received”).  Family members should NEVER select an automated response option. Once a recipient acknowledges a message through an automated response option, attempts to notify the intended individual will cease and this may prevent notification via additional phone numbers or emails.

Marines, civil service, and contrac­tor personnel with a NIPR computer account are required to verify and update their official contact information. NIPR computer users are encouraged to register personal contact information. Mission essential personnel, who are subject to recall, are required to provide all available contact methods in order of priority.

Your ability to benefit from the full spectrum of eMNS capabilities requires self-registration of personal contact information. Entering this information enhances Marine Corps Installations’ ability to rapidly provide emergency information and changes to the base's operating status during non-working hours and when you are away from your desk. A family member’s contact information may also be input.
