Regiment

During the modern era, the word "regiment" – much like "corps" – may have two somewhat divergent meanings, which refer to two distinct roles: In many armies, the first role has been assumed by independent battalions, battlegroups, task forces, brigades and other, similarly-sized operational units. However, these non-regimental units tend to be short-lived; and regiments have tended to retain their traditional responsibilities for ceremonial duties, the recruitment of volunteers, induction of new recruits, individual morale and esprit de corps, and administrative roles (such as pay).
 * 1) a front-line military formation; or
 * 2) an administrative or ceremonial unit.
