On a purple plate, which represents jointness, there are two olive branches in green, symbolizing peace.
Superimposed on them are the elements representing the particularities of Joint HQ Lisbon, its expeditionary character, and the sea-based identity of its parented CJTF HQ.
These two characteristics are represented by a golden ancient Greek galley, which recalls the most famous legendary expedition of Jason and the Argonauts to Colchis, and by an armillary sphere, also in gold, for the navigation skills required to deploy on board a ship.
