Deindividuation can be described as a set of behaviors that a person expresses when he suddenly loses all of his normal identities. A great example of common use of deindividuation is soldiers in the military. The United States Army is known as one of the proudest militaries in the world not because it is effective in combat, but because it demonstrates great teamwork. According to Morris, every soldier enlisted in the United States Army will go through a process of deindividuation (1996). Because after that training period, they will think less about themselves and contribute more to the team's goal, which is the key to success in combat contexts. Everyone will have a new identity, have the same goal and share the same thoughts. Since trainers in boot camp usually do not give much consideration to where people come from or what cultural background they have, some people do not cooperate easily with such changes. Some studies have stated that soldiers who cannot adapt to military environments tend to develop mental disorders, and the reason is closely related to deindividuation. Although the correlation is vague and the data is not enough to convince everyone, deindividuation is still a risky method because not everyone can adapt quickly to changes, especially in case of identity problems and stressful situations.
