Marines (or naval infantry) are military personnel generally trained to operate on both land and sea, with a particular focus on amphibious warfare.
Historically, the main tasks undertaken by marines have included raiding ashore (often in support of naval objectives) and the boarding of vessels during ship-to-ship combat or capture of prize ships.
Crewmen could sign on as naval infantry (called Marinus), rowers/seamen, craftsmen and various other jobs, though all personnel serving in the imperial fleet were classed as milites ("soldiers"), regardless of their function; only when differentiation with the army was required, were the adjectives classiarius or classicus added.
