I like the Navy, they are a  a fleet of waterborne military vessels (watercraft) and its associated naval aviation, both sea-based and land-based.
oh really those have been popular throughout history
yes there are because they are usually a  branch of a nation's armed forces principally designated for naval and amphibious warfare
oh yea that makes sense.
It also involves conducted by surface ships, amphibious ships, submarines, and seaborne aviation
