CTMCM is the Navy way of saying Cryptologic Technician Maintenance Master Chief
Petty Officer. Members of the US
Navy use our rating as a shorthand identification of our job and rank.
For example, Master Chief Petty Officer is an enlisted
paygrade of E-9.
This site isn't about the Navy, though. On this site, we share some of our interests. Our
major interests lie in Genealogy, Geology, and Texas History. Please visit often! Be
