Combat stress reaction, in the past commonly known as shell shock or battle fatigue, is a military term used to categorize 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.
In World War I, shell shock was considered a psychiatric illness resulting from injury to the nerves during combat. 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 56%. Whether a shell-shock sufferer was considered "wounded" or "sick" depended on the circumstances. The large proportion of World War I veterans in the European population meant that the symptoms were common to the culture, although it may not have become popularly known in the US. Combat stress can also affect emergency service personnel when dealing with prolonged incidents or when they deal with major trauma. This leads to an increased depression as they feel that they are not able to function at the level where they can serve the public efficiently and leads to an increased stress.
At INA we realise that this stress and lack of ability to do their work can lead to a feeling of helplessness that means that they need to reach out for support. We Aim to work to provide that support though our work and your donations.
