WotD Laser Targeting

Ok, the group has come up with an idea and since I'm the most vocal with
new weapons I get to post it.

Laser "painting" of targets.

Laser takes 1 action to set up
Squad can make comm roll to unit with GMS, that unit can fire "over the
top" of terrain.

Laser can be mounted in turret or mast of vehicle
Takes 1 action to aquire target with it
Mast counts as single infantry size when being fired at; armour D6
For infantry walkers, mast make walker 1 size larger for targeting

Laser shifts guidance die up one band.
