For the Navy, they have 42" x 2.5"-diameter noodles colored dark battleship gray for all sorts of Navy use onboard their ships. Hey ..... if it ain't a battleship gray foam noodle then it's not standard Navy issue.
Anchors away with a battleship gray foam noodle ....... so many uses onboard with the Navy.
Navy SEALs who don't swim so good will use one as a swim belt for extra flotation to keep them from sinking and keeping up with the other SEALs who are stronger swimmers. Just like those Navy SEALs who don't swim too good ..... a foam noodle swim belt could make all the difference! ....
If anyone actually finds a foam noodle in battleship dark gray designed for military use, it will be a real unusual find. And of course the Army must have one in Army drab green.
So many adults are poor swimmers, unable to swim 100-yards, but tie a foam noodle swim belt around the waist very tight and it turns you into a super swimmer for the side stroke and breast stroke.
