You can post all the bullshit you want about the Coast Guard.Coast Guard History
The Coast Guard's official history began on 4 August 1790 when the first Congress authorized the construction of ten vessels to enforce federal tariff and trade laws and to prevent smuggling. Known variously through the nineteenth and early twentieth centuries as the Revenue Marine and the Revenue Cutter Service, the Coast Guard expanded in size and responsibilities as the nation grew.
The service received its present name in 1915 under an act of Congress that merged the Revenue Cutter Service with the Life-Saving Service, thereby providing the nation with a single maritime service dedicated to saving life at sea and enforcing the nation's maritime laws. The Coast Guard began to maintain the country's aids to maritime navigation, including operating the nation's lighthouses, when President Franklin Roosevelt ordered the transfer of the Lighthouse Service to the Coast Guard in 1939.
While it's a great service, it appears nowhere in the US COnatitution.
Your lameassed idea of more than one Navy indicates what a dipstick you are.
