Combat stress reaction

Combat and Operational Stress Reaction (COSR) is a term used within the military to describe acute behavioural disorganisation seen by medical personnel as a direct result of the trauma of war. Also known as "combat fatigue," it has some overlap with the diagnosis of acute stress reaction used in civilian psychiatry. Historically, it has some link to shell shock, and can sometimes precursor post-traumatic stress disorder.

Combat stress reaction is an acute reaction including a range of behaviours resulting from the stress of battle which decrease the combatant's fighting efficiency. The most common symptoms are fatigue, slower reaction times, indecision, disconnection from one's surroundings, and inability to prioritize. Combat stress reaction is generally short-term and should not be confused with acute stress disorder, post-traumatic stress disorder, or other long-term disorders attributable to combat stress, although any of these may commence as a combat stress reaction.

Combat and Operational Stress Reaction (COSR) are expected and predictable emotional, intellectual, physical, and / or behavioral reactions from exposure to stressful event(s). COSR is not restricted to combat operations. Such reactions may occur as the result of combat like conditions that are present throughout the entire spectrum of military operations to include: training, all phases of the deployment cycle, peacekeeping missions, humanitarian missions, stability and reconstruction, and government support missions.
