Men experience historical events, such as wars, at different times in their lives and are thereby influenced in different ways. Using data on a cohort of veterans from World War II, this study investigates the proposition that entry into the armed forces at a relatively early age maximized discontinuity and facilitated a redirection of the life course through psychological development, a delayed entry into family roles, and greater advancement opportunity. By comparison, later entry into the service favored greater risk of family and career disruption within a pattern of life continuity from adolescence to the middle years. Results from the analysis are consistent with these expectations.
