I would like to make a small remark regarding the representation of fleets and their capabilities. I've played a lot of games of Warplan, but I'm currently losing to a particularly tricky opponent. He had an excellent idea but I find it somewhat contrary to what could have happened in reality, or if Warplan used a system of maritime zones instead of hexagons. The screen image above is explicit: I cannot attack its surface fleet with my last point of operation because its submarines form a sort of close guard that is impossible to cross. If I want to attack it, as I am not adjacent (which is impossible in this case), I am entitled to the message "You cannot occupy the same hexagon as an enemy fleet".

I know this is completely within the rules of the game, but I would like to have your opinion on this situation.
