JOINT BASE CHARLESTON, S.C. –
Petty Officer 3rd Class Isaac Mensah, Navy Operational Support Center Avoca, Pennsylvania Coastal Riverine Squadron quartermaster, performs a backstroke while swimming at Joint Base Charleston, S.C. Aug. 24, 2017. Mensah was training to earn his Second Class Swim Qualification (SCSQ). The SCSQ determines if a person can stay afloat and survive without the use of a personal floatation device. It is used as an entry-level requirement for small boat operators, naval aircrew, and rescue swimmers. The SCSQ consists of a deep water jump, 100-yard swim demonstrating the crawl stroke, breast stroke, side stroke, and elementary backstroke. Immediately after the completion of the swim, students are required to prone float for five minutes and transition to a back float before exiting the water.
