A self-inflicted wound (SIW), is the act of harming oneself where there are no underlying psychological problems related to the self-injury, but where the injurer wanted to take advantage of being injured.
Reasons to self-wound
Most self-inflicted wounds occur during wartime, for various possible reasons.
The most common reason enlisted soldiers self-wound is to render themselves unable to continue serving in combat, thus resulting in their removal from the combat line to a hospital. Thus, self-injury can be used to avoid a more serious combat injury or a combat death.
Types of wounds
Among the most common type of wounds are a rifle shot to the hand, arm, leg, or foot.
Wounds can also occur by deliberate neglect of health, e.g. by failing to treat a minor wound that will become infected, or "forgetting" foot care in damp conditions that lead to fungal infections.
In most militaries, deliberately self-inflicted wounds are considered to be a serious military offense. Most self-inflicted wounds go unnoticed, though consequences are often severe if caught.
In the British army during World War I, the maximum penalty for a self-inflicted wound ("Wilfully maiming himself with intent to render himself unfit for service" as it was described) under Section 18 of the Army Act 1881 was imprisonment, rather than capital punishment. In the British Army, some 3,894 men were found guilty, and were sent to prison for lengthy periods.
In Nazi concentration camps, self-injury was dangerous as the incapacitated were often just executed, but in some lower-stringency camps it has indeed been documented.
