During UNREP, what color jacket is assigned to the Signalman?

The Signalman is assigned a green jacket during an underway replenishment (UNREP) operation. This color-coding is consistent across naval operations to designate specific roles and responsibilities of personnel to enhance safety and efficiency on deck. The green jacket indicates that the wearer is involved with signal operations, which include directing and communicating with other vessels. This role is critical during UNREP to ensure proper coordination and to minimize the risk of accidents while transferring fuel, supplies, or personnel between ships. Proper identification of personnel through color-coded jackets helps maintain clear communication and situational awareness on operations at sea.
