It is with combined forces from 150+ countries that there is a concerted effort to thwart crime on the high seas ... a very historical venture that in other periods was also known as piracy-on-the-high-seas - and, which caused several countries to establish naval presence as escort contingents for commerce-and-trade enterprises : see MSO and MOOTW; and, Rules of Engagement ROE.
Admiralty Warrants developed out of western Europe (i.e., Great Britain) as a monarchical endorsement / writ under these said circumstances to intercept these thugees and pirates.
In the 21st century, Operation Artemis serves in the capacity of safety on the high seas intercept services / the Admiralty Warrant. NATO - 2 is the western bloc security and defence network / now also see the European Union's specific common S&D alliance : CSDP.
