Following up on the, ehem, Navy boat, here's the 1960 Landing Party Manual, the last publication from the US Navy on sailors operating as ground forces, their organization, and equipment. There was apparently a 1962 revision, but as most things, if it isn't very early in the year/I can't find it, 1960-1961 material suffices.
