Crewman
From Halopedia, the Halo wiki
Template:Rank Infobox Crewman is the third enlisted rank of the UNSC Navy, equal in rank to Lance Corporal in the UNSC Marine Corps. They are not trained or equipped for battle. In fact, they will only use M6D Pistols whenever trouble starts. Many crewmen wear different colors to their uniforms depending on what their job is aboard the ship. Grey-uniformed crewmen are the Command Crew. Orange is the color for the Engineering Crew. Any shade of yellow are part of the Tech/Ops Crew. Every ship needs to be secure, which is why red-uniformed crewmen work as the Security Crew. The Science Crew, donned in blue, studies science or biology aboard the ship.
