Which rates are compressed to become CUCM?

The correct answer is that the EACS, BUCS, and SWCS rates are compressed to form the CUCM (Chief Utilities Communication Manager). In this context, compression of rates refers to the reorganization or consolidation of similar duties and responsibilities under a single rating title.

EACS (Engineering Aid), BUCS (Builder), and SWCS (Steelworker) all belong to occupational areas related to utility and construction work in the Navy. The CUCM encompasses a broad range of management and technical skills relevant to the fields covered by these ratings, allowing for a more efficient and cohesive approach to training and responsibilities within the community.

The other options consist of rates that either do not relate to the utility and construction domains or do not compress into the CUCM as defined in the Navy’s rating system. For instance, ICCM (Interior Communications Electrician), EMCM (Electrician's Mate), and BMCM (Boatswain’s Mate) each cover distinct technical fields that aren't aligned under the CUCM umbrella. Similarly, MMCM (Machinist's Mate), SCPO (Supply Chief Petty Officer), and YNCM (Yeoman Chief Petty Officer) represent different specialties that do not compress into the CUCM rating.
