What does CBMU stand for and what is its primary mission?

The term CBMU stands for Construction Battalion Maintenance Unit, which reflects its role in supporting naval construction forces. The primary mission of a CBMU is to operate and maintain public works and utilities, ensuring that vital infrastructure and services are effectively managed and sustained. This includes tasks such as repairing and maintaining roads, water systems, and electrical utilities, which are essential for both combat and humanitarian operations.

In contrast to the other options, which suggest various forms of combat or base management that do not align with the specific functions of a CBMU, the correct answer highlights the unit's direct involvement in construction and maintenance activities. Understanding the mission of a CBMU is critical for Seabees, as it aligns with their overall objectives of providing support and ensuring operational readiness through effective infrastructure management.
