# Mexeflote as Wikipedia:
The Mexeflote is a landing raft used by the British Royal Logistic Corps and the Royal Australian Navy to move goods and vehicles between ship and shore. It was first used by British military in the 1960s. It was used during the Falklands conflict, and has been used in humanitarian aid missions.
