Lastly we argue during our gameplay how to approach the M.A.R.K. 14 special ability "Grenade launcher".
The card with the ability says that is a range attack. So is that mean M.A.R.K. 14 needs to have line of sight to be able to use this ability or not?
Second related question is what if the targeting model is covered from by the ceiling of the building? Is the grenade possible hit the target?
