The term 'Halyard Supporters' refers to members of the SPARS, which stands for the United States Coast Guard Women's Reserve. The SPARS was established in 1942 and was the first branch of the U.S. military to accept women into its ranks. Halyard Supporters were responsible for providing support services to the Coast Guard during World War II, such as communications, medical care, and administrative duties. They also served as a morale booster for the troops, providing entertainment and recreational activities.
