Wounded in action (WIA) is a military casualty classification used to describe military personnel who are injured in combat but who did not die from their wounds.[1] The term is closely related to other casualty classifications, such as killed in action (KIA), died of wounds (DOW), and missing in action (MIA).
Definitions
The precise definition of "wounded in action" varies slightly among different military organizations, but generally refers to personnel who have sustained a wound or injury in a combat zone that requires medical treatment.
United States Department of Defense
The United States Department of Defense defines a WIA as a battle casualty who has incurred a wound or injury due to hostile action and requires medical treatment. To be classified as WIA, the injury must be severe enough to require evacuation from the combat area or hospitalization.[1] Personnel who are injured in non-combat incidents (such as training accidents or vehicle crashes) are not classified as WIA.
NATO
According to NATO standard terminology (AAP-6), a battle casualty is any person who is lost to the organization by reason of having been declared dead, wounded, injured, diseased, interned, captured, retained, missing, or dropped from the rolls. WIA specifically covers those who are evacuated for medical treatment due to combat wounds.[2]
Related classifications
- Killed in action (KIA): Personnel killed outright by hostile action.
- Died of wounds (DOW): Personnel who survive initial hostile action but later die from their injuries. In some contexts, this is a sub-category of WIA.
- Missing in action (MIA): Personnel whose whereabouts and status are unknown.
- Prisoner of war (POW): Personnel captured by enemy forces.
Medical evacuation and treatment
Advances in military medicine, such as the widespread use of MEDEVAC (medical evacuation) helicopters, have significantly increased survival rates for WIA personnel in modern conflicts. The "wounded-to-killed ratio" (WKR) is often used by military strategists to measure the effectiveness of battlefield medical care; a higher ratio indicates that more personnel are surviving their injuries.[3]
Recognition and awards
Many nations have specific awards to recognize personnel who are wounded in action.
- In the United States Armed Forces, the Purple Heart is awarded to those wounded or killed by enemy action.[4]
- In the United Kingdom and many Commonwealth countries, a Wound Stripe is worn on the uniform to denote a wound received in action.
