A military brat (colloquial or military slang) is a child of serving or retired military personnel. Military brats are associated with a unique subculture and cultural identity. A military brat's childhood or adolescent life may be immersed in military culture to the point where the mainstream culture of their home country may seem foreign or peripheral. In many countries where there are military brat subcultures, the child's family moves great distances from one non-combat assignment to another for much of their youth. For highly mobile military brats, a mixed cultural identity often results, due to exposure to numerous national or regional cultures.
War-related family stresses, including long-term war-related absence of a parent, as well as war aftermath issues, are common features of military brat life in some countries, although the degree of war-involvement of individual countries with military brat subcultures may vary.
