cuerpo de ejército

A corps is an organizational unit that was popularized as a military innovation by Napoleon, who formally introduced it in 1800 as a way to divide large armies into smaller, more manageable formations. The term comes from French and Latin words meaning "body," and while the concept existed in earlier armies, it only became a standard military structure once armies grew large enough to require such division.
