Marine

Marine is an umbrella term for things relating to the ocean, as with Marine biology, Marine geology, and as a term for a navy, etc. In scientific contexts, the term almost always refers exclusively to saltwater environments, although in other contexts (e.g., engineering) it may refer to any (usually navigable) body of water.

Military

A Marine is an armed services member whose primary function is to assault land from the sea in amphibious warfare. Different nations have more-expanded or more-limited roles for their particular forces, but the core role remains the same. Traditionally, Marines served on board warships and fulfilled numerous roles: They assisted the crew in battles against other warships, conducted small coastal raids, and protected the officers from mutiny by the crew.

In modern warfare, Marines are often highly mobile, elite troops that can be positioned offshore close to the war zone to launch amphibious assaults. Maneuver warfare is a type of fighting used by the US Marine Corps, which allows the battle to quickly change on the go and in turn keeping the enemy off balance at all times. Communication is key to this form of warfare.
