Reasonable Sufficiency is an ambitious military novel depicting battles on land, air, sea, and within the minds of men dealing with adverse physical conditions and heated political circles. The occasional weekend warrior will appreciate the smartly structured storyline, Glueck's colorful delivery, and vivid characters, such as Lee Wilson, the wide-eyed Everyman who finds himself in the middle of the action. The Rambos of the reading community will note Glueck's obvious talent as an astute researcher, paying great attention to battle, weaponry, and geographical detail. In the end, the Rambos will cheer not only for the stouthearted Captain Dell Janson but author David Glueck as well.
