U. S. Navy
Enlisted men’s specialty marks, distinguishing marks and buttons

The Branch of the Navy to which all enlisted men not petty officers belong is shown by a branch mark, a stripe of braid three-eighths of an inch wide around the top of the sleeve at the shoulder seam.

For the Seaman Branch the branch mark is worn on the right arm, in blue for white clothing and white for blue clothing; for the artificer branch, engineer force, the branch mark is worn on the left arm in red. Hospital apprentices, shipwrights, musicians, buglers, commissary and messmen wear no branch mark.

Service stripes.—To show the number of enlistments that a man has served all enlisted men who have served one or more enlistments of three or four years wear service stripes, three-eighths of an inch wide, diagonally across the outer side of the left sleeve of the blue coat, white coat, overshirt or jumper. These service stripes are of scarlet cloth on blue clothing and of blue cloth on white clothes. One service stripe is worn for each enlistment of three or four years that the wearer has completed. For petty officers who hold three consecutive good-conduct badges the service stripes are made of gold lace braid.

Neckerchief.—The neckerchief worn by enlisted men with the blue overshirt and white dress jumper is of black silk thirty-six inches square, worn around the neck under the collar, tied in a square knot just below the collar opening in front.

Leggings.—For duty with landing forces ashore enlisted men of the navy wear khaki-colored canvas leggings.
