The Navy Working Uniform (NWU) is a utility uniform with multiple pockets on the shirt and trousers. Three versions of the uniform exist, each with a multi-color digital camouflage print pattern similar to those introduced by other services. Type I is predominantly blue with some gray for the majority of sailors. It was originally developed for shipboard use, but proved unsuitable for shipboard environments and was discontinued in 2019. Type II is a desert digital pattern currently restricted to SEALs and other sailors such as Seabees assigned to Naval Special Warfare Units when in desert environments. Type III is a woodland digital pattern for sailors in shore commands and riverine units. The camouflage patterns are similar to the MARPAT worn on the Marine Corps Combat Utility Uniform by U.S. Marines.
