Through the Corps series (Semper Fi, 1986; Call to Arms, 1987; Counterattack, 1990; Battleground, 1992, Line of Fire, 1992; Close Combat, 1992; Honor Bound, 1994) we see the development of a large number of officers and men; there are considerably more characters who are given some development than in the Brotherhood of War (1983-1988) or Badge of Honor (1988-1995) series. The focus shifts between novels; for example, in the latest novel in the series the action takes place in Argentina, not Europe or the Pacific, and few of the previously major characters — the McCoy brothers, the Pickerings (father and son) among them — are featured prominently. Other venues for action in the series include Australia, Guadalcanal, the U.S., and New Guinea. Some characters rise through the military hierarchy, such as Stecker and Pick's father Fleming Pickering.
