Navigator (Alien Rank)
A Navigator is one of the lower Alien Ranks, and is one of the more commonly encountered types in most mission profiles. Their role on board is presumed to be to guide the UFO from the source of the alien attacks to Earth, and then to the particular mission target, freeing up the rest of the crew to other tasks. Navigators are commonly found near the bridge and UFO Navigation, but often move away if they have reason to.
In combat a Navigator is the equal of the soldier but no better, except for a slightly increased intelligence. The only exception to this is Muton Navigators who wear slightly better armour than their lower ranked colleagues.
