Military Intelligence contains both a narrative branch history and the lineage and honors for 108 Regular Army, Army Reserve, and Army National Guard military intelligence units-brigades, groups, and battalions, the echelons authorized distinctive heraldic items. Based on official records attesting to the history of the respective units, John Patrick Finnegan and Romana Danysh ably capture the organizational evolution of the Military Intelligence Corps. Mindful of safeguarding intelligence sources and methods, Finnegan makes no pretense at discussing the operational aspects and the complex interrelationships between Army intelligence and other organizations in the intelligence community. His focus is on the slow development and eventual emergence of professional Army intelligence organizations and functions. The lineage and honors complied by Danysh and the colorful heraldic items foster unit pride, thereby enhancing esprit de corps among the thousands of military intelligence specialists now serving their nation. The military intelligence story, a relatively unknown part of the Army's heritage, is a story worth reading.
