The Regional Security System (RSS) is a defence and security pact of seven Eastern Caribbean island nations, and its Air Wing received this C-26A Metro from the USA in 1999 (ex 86-0454). It visited Hato again for counter narcotics operations in March 2004. Compared to its previous visit it had received a new dark grey paintjob, a huge sharkmouth and badge of the Air Wing, which had adopted the nickname Warlocks.
