Since the USMC SIPR accounts are all on the MCW domain (HCS), the account creation process is different than USMC NIPR, see below.
USMC MCEN-S account holders.
If you know you have an account, proceed to Step 2, as long as your account is valid and up to date. Contact your local ISC for support.
Coordinate with corresponding USMC sponsor and have them submit for an account using the method below.
Follow local command policies for obtaining a SIPR account via Remedy . Contact the MCEN Battle Captain for assistance as they can submit an account for those without Remedy access. Contact via phone @ 703-784-5300 or via email.
Once the account is created, user can log in to https://mccast2.mceits.usmc.smil.mil/ and submit a MCCAST Support Request.
