Dr. Graham Turbiville's account of U.S. military engagement with Mexico provides a broad account of the interaction among the military elements of both countries from 1846 to the present day. He describes the evolution of the Mexican military toward a more capable and modern force. Especially informative for the special operations reader is the advent of numerous special operations units within the military and some civil elements. As noted, this has fostered reciprocal opportunities for SOF training and education.
