Question:
What is the RE equivalent for transport purposes (both naval and air) of a unit transporting one resource point? Is it the RE size of the unit plus one or only the RE size of the unit if it is a division (so the resource point is less than half of the RE size of the unit) or what?

Answer:
Ground units may not carry resource points while being transported by naval or air transport, they may only carry resource points overland. Resource points and units are counted separately when shipped as naval or air cargo.
