The game Instruction Manual revision 5 for NCP 1.01 states, "A Supply Wagon or transport ship is able to supply any land unit with both General Supply and Ammunition if it is in the same or an adjacent region."
Instruction Manual (Version 6.2 for NCP 1.02) states that supply wagons' "supply points may be used to provide supply
to any force located in the same region as the Supply Wagon."
I am playing version 1.04b. Which is it?
