A regular army refers to the official, structured military force of a state, distinguished from irregular forces by its permanent organization, training, and hierarchical command. It typically includes a standing army maintained during peacetime and a reserve force activated for war, existing in both conscript and professional models. Authors such as Lord Ernest Hamilton emphasized its role in national honor, while Hubert Foster underscored its readiness during peacetime and its ability to scale up during conflict.
Friedrich von Bernhardi contrasted regular troops with forces organized during mobilization periods, and Émile Gaboriau praised the enduring strength of regular infantry throughout history. These viewpoints collectively highlight the regular army’s dual function as a stabilizing institution and a fundamental pillar of state authority, in stark contrast to the improvised character of irregular forces.
