An interesting variation on the point; but nothing got paired multiple times at once. Good call.
I refer to both TAC+FIG and ART+MAN as a “combat pair” (or if confusing, “air pair”) when I roll–but that pairing concept 1:1 is the key I think.
When an aircraft leaves a coastal territory or island, does it cost one point to move into the sea zone adjacent to the territory/island? for example, If a plane leaves Japan on the pacific map, does it cost one movement point to move in to sea zone 6? The way I read the rules, it does.
Yes, it does cost a movement point.
