overnight. The admission of a newborn occurs at the time of birth.

BATTLE CASUALTY - One missing from his unit as a result of death, injury, illness, or
capture that occurred in action. "In action" characterizes the casualty status as having
been the direct result of hostile action; sustained in combat or relating thereto; or sustained
going to or from a combat mission provided that the occurrence was directly related to
hostile action. Included are persons killed or wounded mistakenly or accidentally by
friendly fire directed at a hostile force or what is thought to be a hostile force. However,
injuries due to the elements or self-inflicted wounds and, except in unusual cases, wounds
or death inflicted by a friendly force while the individual is in an AWOL or dropped from rolls
status or has voluntarily absented himself from his place of duty are not to be considered
as sustained in action and thereby not to be interpreted as battle casualties.
