Per MARADMIN 062/26, the Marine Corps is transitioning to the Alert! Mass Warning and Notification System (MWNS), which supersedes the legacy ATHOC system. All personnel in the Primary Population are required to enroll in Alert! and must verify and update their information at least every 90 days.
This population includes Department of War (DOW) military, civilians, and contractors whose normal place of duty is on a DOW Installation or within a DOW Facility. This information must include a means for after-duty hours personal contact.
Mission essential personnel subject to recall are required to provide all available contact methods in order of priority.
The Secondary Population, which includes family members, guests, and visitors, is also highly encouraged to enroll to receive emergency notifications.
Personnel can enroll or update their information by using the Alert! PC client, found in the workstation system tray, or by signing into dod.alert.mil. The new system provides a single point of entry for all users, and enrollment should be integrated into unit check-in and check-out procedures.
Only those with usmc.mil email accounts can self-register to receive alerts. MNS administrators should work with affected commands and tenants to manually enter non usmc.mil users into the MNS system in order for them to receive alerts.
