"Unit cohesion can be considered a contributor to morale. Manning reviews various definitions of the terms morale and esprit de corps and suggests that morale is best thought of as “the enthusiasm and persistence with which a member of a group engages in the prescribed activities of the group” (Manning, 1994). He suggests that esprit de corps is the counterpart to cohesion at the level of the organization rather than at the level of the primary unit and that cohesion and esprit de corps are each contributors to one’s morale."
