A soldier so hardcore even the Navy keeps them on a leash called ships.

means Of or relating to the sea, or a member of a military force trained to fight at sea and on land, typically deployed from ships.

from From Latin 'marinus' (of the sea), from 'mare' (sea) — the same root that gives us 'maritime' and 'mariner.' The sea-creature sense ('marine life') and the soldier sense split off from the same source: troops stationed aboard ships for naval warfare were called marines by the 17th century, since they served at sea even though they were fundamentally infantry.
