According to Wikipedia: "Combat engineers are a key role in all armed forces of the world, and invariably found either closely integrated into the force structure, or even into the combat units of the national troops. In many countries, combat engineers are members of broader military engineering corps or branches. Examples of this include the Royal Australian Engineers, The Corps of Royal Canadian Engineers (new designation for the Canadian Military Engineers as of July 2013), German military engineers the Irish Army Engineer Corps, the Corps of Engineers, Indian Army, the Corps of Royal New Zealand Engineers, the Pakistan Army Corps of Engineers, the Corps of Royal Engineers, and the United States Army Corps of Engineers. However, some nations have distinct combat engineering corps or branches which are separate from other types of military engineers. The Danish military engineering corps is almost entirely organized into one regiment of combat engineers, simply named Ingeniørregimentet ("The Engineering Regiment")."
