Try to imagine if you will, a broad daylight assassination of some ordinary Joe Smith, a man who perhaps saw something the Mob would rather he not have seen. The contract killer is a reasonably well trained shooter (skill 14) who has access to van, and has successfully followed the victim into a long term parking lot at the airport. The van door opens up unexpectedly, and inside is the assassin with a laser sight device under his silenced 10mm Glock 20.

Range at which an unsilenced Glock 20 can be heard is presumed to be 512 yards (analogous to a .45 caliber gun).

Now further imagine that the target is moving north towards the airport terminal, and is in the open as he walks in the area that cars travel through in order to pull into parking slots. The assassin is firing at him from a van with its panel door open sufficiently wide enough to permit the shot, but not too wide to expose to casual view, the shooter inside. The door is facing East (time is 3PM if that helps) and the range to target is 10 yards.

Attached silencer to the gun is worth a -3 penalty to hearing rolls.

Identify the hearing rolls required by:

Someone inside the airport terminal whose "walls" are thick glass some 40 yards away from the shooter.

Someone inside the airport terminal's entrance way where people are dropped off and picked up via cars and light traffic is passing by.

Someone who is east of the van and some 25 yards away.

Someone who is west of the van some 10 yards away (don't forget, the van's exterior counts as a wall between the shooter inside the van and the outside potential witness)

Assume that everyone is minding their own business (un-alert) or bored (ie security guards at the entrance to the airport terminal who have been on duty for the last 2 hours).

I think you'll be surprised at the total modifiers involved, especially with the penalties for silenced and outside the cone of sound (for an overall -6 just to start).
