Stripe, but in inverted colors (i.e., broad blue stripe with narrow white and CG red stripes) and the Auxiliary shield. Similar racing stripe designs have been adopted for the use of other coast guards and maritime authorities and many other law enforcement and rescue agencies. Uniforms For most of the Coast Guard's history its uniforms largely mirrored the style of U.S. Navy uniforms, distinguishable only by their insignia. In 1974, under the leadership of Admiral Chester R. Bender, the initial versions of the current Coast Guard Service Dress Blue and Tropical uniforms were introduced. This represented a major departure from many common conventions in naval and maritime uniforms. Notably, "Bender's Blues" were a common service dress uniform for all ranks, dispensing with the sailor suit and sailor cap formerly worn by enlisted members. Rank insignia remained consistent with the naval pattern and some distinctly-nautical items such as the pea coat, officer's sword, and dress white uniforms remained. Today, the Coast Guard's uniforms remain among the simplest of any branch of the armed forces, with fewer total uniforms and uniform variants than the other armed services. There are only three uniforms that typically serve as standard uniforms of the day—the Operational Dress Uniform, Tropical Blue, and Service Dress Blue (Bravo). Coast Guard Reserve The United States Coast Guard Reserve is the reserve military force of the Coast Guard. The Coast Guard Reserve was founded on 19 February 1941. The Coast Guard has 8700 reservists who normally drill two days a month and an additional 12 days of active duty each year, although many perform additional drill and active duty periods, to include those mobilized to extended active duty. Coast Guard reservists possess the same training and qualifications as their active duty counterparts, and as such, can be found augmenting active duty Coast Guard units every day. During the Vietnam War and shortly thereafter, the Coast Guard considered abandoning the reserve program, but the force was instead reoriented into force augmentation, where its principal focus was not just reserve operations, but to add to the readiness and mission execution of every-day active duty personnel. Since 11 September 2001, reservists have been activated and served on tours of active duty, to include deployments to the Persian Gulf and also as parts of Department of Defense combatant commands such as the U.S. Northern and Central Commands. Coast Guard Port Security Units are entirely staffed
