FMB Quest - Setting Up Targets

[Racetrack]

Ok, in the first case Reds win if they destroy all the 3 bridges right?
If they Destroy only 2 bridges Blues wins right?
In the second case, what happen if the Target Area cover ALL the moviment of the concoy?
I mean that the convoy will rest in that space for all the time....
For the points... If I'm a Red and I destroy a bridge that is a Primary Target then I score points.. But what happens if blues wins for the points? Who score points?
The meaning of this questions is to create a mission where if the Red win score points, if the blue wins score point...
