A retired Special Forces officer who spent three years teaching cadets at The Citadel has published his first novel – a fictional tale of a clandestine operator named Pike Logan who must intercept an attack planned, not by a terrorist group or organization, but by two men operating independently and in possession of a powerful weapon.   Brad Taylor, a retired lieutenant colonel in the Army’s elite Special Forces, will sign copies of “One Rough Man” from 1 to 3 p.m. on Monday and Tuesday March 7 and 8 at The Citadel Bookstore inside Mark Clark Hall. The book will be released nationwide on Feb.
