Which form is used to document casualty data, injuries, and medical interventions?

The correct form used to document casualty data, injuries, and medical interventions is the DD Form 1380. This form is specifically designed for battlefield and tactical situations to provide immediate, on-the-spot data regarding the condition of injured personnel. It allows medical personnel to quickly record critical information about casualties, including vital signs, type of injuries, and any medical interventions performed. The significance of this form lies in its ability to ensure accurate and timely communication of essential medical information, which is crucial for further treatment and care.

The other forms listed are used for different purposes and do not serve as a casualty reporting tool. For instance, DD Form 1382 is related to patient movement and evacuation, while DD Form 1480 is focused on indicating suitability for duty. DD Form 1830 is used for reporting medical supplies and equipment. Therefore, the comprehensive utility of DD Form 1380 in recording casualty data distinctly positions it as the correct answer for the question stated.
