Morale

Morale (also known as esprit de corps (French pronunciation: ​[ɛspʀi də kɔʀ])) is the capacity of a group's members to maintain belief in an institution or goal, particularly in the face of opposition or hardship. Morale is often referenced by authority figures as a generic value judgment of the willpower, obedience, and self-discipline of a group tasked with performing duties assigned by a superior. According to Alexander H. Leighton, "morale is the capacity of a group of people to pull together persistently and consistently in pursuit of a common purpose". Morale is important in the military, because it improves unit cohesion. Without good morale, a force will be more likely to give up or surrender. Morale is usually assessed at a collective, rather than an individual level. In wartime, civilian morale is also important. Esprit de corps is considered to be an important part of a fighting unit.

An American general defined morale as "when a soldier thinks his army is the best in the world, his regiment the best in the army, his company the best in the regiment, his squad the best in the company, and that he himself is the best blankety-blank soldier man in the outfit."

In military science, there are two meanings to morale. Primarily it means unit cohesion: the cohesion of a unit, task force, or other military group. An army with good supply lines, sound air cover and a clear objective can be said to possess, as a whole, "good morale" or "high morale." Historically, elite military units such as special operations forces have "high morale" due to both their training and pride in their unit. When a unit's morale is said to be "depleted", it means it is close to "crack and surrender". It is well worth noting that generally speaking, most commanders do not look at the morale of specific individuals but rather the "fighting spirit" of squadrons, divisions, battalions, ships, etc.
