TRANSPORT UNIT :
I would like a new fast unit (ex: pellican: 104,4 Km/h / YAN: 34,8 km/h / NEW UNIT : about 70-75 km/h) capable of carrying the other units.
In practice, this new unit would have notches under its icon (like strategic units), but it's not a strategic unit.
Instead of conferring greater strength to the other units that aggregate to it, this new unit gives them its own speed (To represent that it is carrying these units on it).
So, for example, if this new unit is able to aggregate with 100 infantry units :
by sending 1 New unit + 100 infantry, the whole squad will travel at the speed of the new unit !!
by sending 10 new units + 1000 aggregate infantry = all units will run at 75 km/h !!
if you make the mistake of selecting 10 new units + 1002 infantry ... The 2 excess units will stay on foot (They can not be boarded) ... and thus they will preclude the speed bonus for the whole expedition!
