 CB is the nickname for construction battalion, and they are the Navy's construction company. When they're in combat zones, they go before the Marines to build whatever is needed to start the mission. The Naval Mobile Construction Battalion 4 is here in SOSBO to help fortify the base and keep it mission ready. In a way, kind of like just having a small town. Everybody knows everybody's debt, just like the entire rest of the Navy. It's just a melting pot. We've got people who've been in construction and done this type of work before, and we've got people who've never ever been in construction. Having a small community made up of different viewpoints allows the CBs to get the job done quicker. I like being a CB because it's such a diverse group of people that we always work really hard to get the job done in such a short amount of time.
