soldier wiki:
dier is a person who has enlisted with, or has been conscripted into, the armed forces of a sovereign country and has undergone training and received equipment (such as a uniform and weapon) to defend that country or its interests. In most countries, the term soldier is limited to such people who serve in the land branch of the armed services (usually known as the army). Armies are strictly hierarchical societies, and within them, groups of soldiers are usually divided into military units of some kind.
