His illustrious career also included combat service in Korea and Vietnam and resulted in his becoming one of the most decorated graduates of the Corps of Cadets. During his Korean tour, General Hollingsworth developed his famous short-war concept, which became the example of the U. S. Army’s forwards defense concept.
While serving as liaison to the chief of staff in Washington, D.C., he created a program that doubled the number of scholarships given to ROTC students. A 1980 distinguished alumnus of Texas A&M, he served as president of Hollingsworth Consultants.
