The US Navy is one of the seven services for which the Congress commissions an Officer corps.

To provide and maintain a Navy;

When I was aboard ship or at Naval Bases, they had signs which said for Military and Naval Officers Only.

Even Trump supporters recognize that this means that the Navy is not Military.

President Trump recently said that the removal of illegal immigrants was a "military operation" several news media people criticized his poor choice of words.

Most of those people think "boots on the ground" means soldiers in the field and the Navy is Military.
