Identification tags ( dog tags) for soldiers appear to be one of the most under-studied and neglected areas of research. In battles the only identifying object is a metal identification tag that has the information about the soldier worn it. To find and identify those killed, the entire war zone have to be searched to find dead bodies or these identification tags. This task is not only time-consuming but also costly and needs a lot of manpower to search the area. In this paper an electronic device is designed and implemented to replace identification tags and to help finding killed or injured soldiers as soon as possible during the war or after it. A light, power efficient and robust positioning module that provides a high accuracy in all environments is needed to find soldier position. Although GPS has weaknesses but it can provide sufficient accuracy while meeting the above requirements. RF transmission is used to send data to operation center. And a low consuming 32 bit ARM microcontroller is used for circuit timing and data processing as well as keeping soldier basic and medical information. The battery life of this device is important. All the electrical equipment used in this device is low power consuming and with the written algorithm the device can work for months.
