Dunbar is the son of Kaylyn M. and David A. Dunbar of St. Helena Island. Walker is the daughter of Maurice and Camile Cornish of Beaufort.
The Delayed-Entry Program allows recruits to enter the Navy and take as long as one year to complete commitments, such as high school. Using recruiters as mentors, the program helps ease the transition from civilian to military life, according to a news release.
Dunbar and Walker will report for active duty to undergo basic training at the Navy's Recruit Training Center in Great Lakes, Ill.
