You real Navy guys out there will understand this.
You civilians will now know what each of the ranking insignias really mean.
On the second row, the Eagles are lovingly known as ‘Crows.’
The crossed anchors on the first three crows are Boatswain’s Mates; they know everything about paints, red-led primer, chipping and painting, polishing brass, driving the ship (helmsman), knots, brooms and swabs (mops).
The second set of crows are Chiefs, and, in this case, the insignia is that of a Quartermaster – the keeper and updater of all charts (maps) and other navigational stuff that the officers have no clue about.
The insignia under the crow lets other sailors know what job they perform.
Now ya know!!!
