Out of Sight 40k6 pg 16
If there are no visible models in the target unit, all remaining Wounds in the pool are lost and the shooting attack ends.
Context: During first turn of 3k game Havoc squad could see one wraith that was visible. If it was the only model visible and died before the Wound Pool was exhausted all other wounds would not have hit Destroyer Lord or other wraiths. (However laser pointer indicated that Destroyer Lord could be seen from targeting unit. Rule was not put into effect) I'm personally looking forward to this rule coming in effect some game.
Side note: Yay! No more JFK bullets like in 5th.
Vehicles and Overwatch 40k6 pg 76
Unless specified otherwise, vehicles cannot make Overwatch fire -- it takes too long to bring their weapons to bear.
Context: 3k game Destroyer Lord with Canoptek Wraiths assaulted a Plague Marine Rhino. It was asked if vehicles can perform overwatch.
Transports and Assaults 40k6 pg 80
If a Transport vehicle is assaulted, an embarked unit can fire Overwatch at the attackers out its Fire Points.
Context: Destroyer Lord and Canoptek Wraiths were assaulting aforementioned Plague Marine Rhino. We learned the embarked Plague Marines could perform Overwatch on the assaulting Necron unit. Two Marines were able to shoot due to Rhino having 1 fire point.
