<unk>  <unk>  is a term used within the military to describe acute behavioral disorganization as a direct result of the trauma of war. Also known as<unk>  fatigue", "battle fatigue", or "battle neurosis", it has some overlap with the diagnosis of acute<unk><unk>  used in civilian psychiatry. It is historically linked to shell shock and can sometimes precurse post-traumatic<unk>  disorder.<unk>  is an acute<unk>  that includes a range of behaviors resulting from the<unk>  of battle that decrease the<unk> ant's fighting efficiency. The most common symptoms are fatigue, slower<unk>  times, indecision, disconnection from one's surroundings, and the inability to prioritize.<unk>  is generally short-term and should not be confused with acute<unk>  disorder, post-traumatic<unk>  disorder, or other long-term disorders attributable to<unk><unk> , although any of these may commence as a<unk> . The US Army uses the term/acronym COSR<unk>  in official medical reports. This term can be applied to any<unk><unk>  in the military unit environment. Many<unk> s look like symptoms of mental illness (such as panic, extreme anxiety, depression, and hallucinations), but they are only transient<unk> s to the traumatic<unk>  of<unk>  and the cumulative<unk> es of military operations. In World War I, shell shock was considered a psychiatric illness resulting from injury to the nerves during<unk> . The horrors of trench warfare meant that about 10% of the fighting soldiers were killed (compared to 4.5% during World War II) and the total proportion of troops who became casualties (killed or wounded) was about 57%. Whether a shell-shock sufferer was considered "wounded" or "sick" depended on the circumstances. When faced with the phenomenon of a minority of soldiers mentally breaking down, there was an expectation that the root of this problem lay in character of the individual soldier, not because of what they experienced on the front lines during the war. The large proportion of World War I veterans in the European population meant that the symptoms were common to the culture.
