Editing Warhammer 40,000/10th Edition Tactics/Tau (section)

==Faction Rules==
*'''For the Greater Good''': IT'S BACK!!! Whenever a unit shoots, you can have a second unit that is also eligible to shoot act as a Observer and mark an enemy that both of your units can see. The shooter gains +1 to BS and if the observer has the {{W40kKeyword|Markerlight}} keyword, the shooter also gains '''Ignores Cover''' on their attacks. This creates an interesting dynamic between less important shooting and more crucial stuff, with anyone being able to pitch in and help their budy get their rounds on target. Essentially you're setting up a modern target acquisition kill chain, so Tau continue the tradition of being the closest to modern real world tactics.
**Importantly this modifies the Ballistic Skill, not the hit roll, meaning that this stacks with things that give +1 to hit. For example if a Stormsurge remains stationary during the movement phase to get +1 to hit for its heavy weapons, and then in the shooting phase you guide it with another unit, it will be hitting on a 2+.
**Note that this has no restrictions on how often this can be used, meaning it can be used at any time so long as each unit only acts as an observer or shooter once. While it's not giving two walls of pulse rifles firing overwatch, the one unit that does shoot can do so much more reliably.
