There's three types of submarines in the game and they are a little bit more specific like some others units.
A submarine is often hidden... if he lugs around alone or ... in some quantities in a FMCTU (a kind of division that contains only one kind of unit ).
It's not the case in a FMB (a kind of army that contains several types of units).
I know that the appendix is not there, but some few terms to introduce it.
In the game and on the map, there's no pawn positions for them (they are invisible in a FMCTU).
So... I'm just buzzy to modify the system (how can we fixed there positions without pawns and there movements).
They are very specifics, your hidden enemies ... is watching you !
