The modern Coast Guard uniform represents a break from many traditions in the name of comfort and utility. No longer are iconic sailor uniforms of old used by the Coast Guard. The change was due in part to a long-seeded desire within the Coast Guard to distinguish itself from the U.S. Navy.
The Operational Dress Uniform (ODU) is the normal work uniform of the United States Coast Guard, the United States Coast Guard Auxiliary, the National Oceanic and Atmospheric Administration Commissioned Officer Corps, and the United States Public Health Service Commissioned Corps. It is also one of the uniforms worn by the New York Naval Militia.
The Marine Corps Combat Utility Uniform (MCCUU) is the current battledress uniform of the United States Marine Corps. It is also worn by Navy personnel (mostly corpsmen, chaplains, and their bodyguards) assigned to Marine Corps units (e.g. the Fleet Marine Force).
The NWU Type I is intended for year-round wear and is the standard working uniform ashore. Components of the uniform include: a unisex shirt and trousers, unisex eight-point cap, 9-inch leather safety boots, Navy blue undershirt and cotton or nylon web belt.
