I'm not sure where you're getting those numbers from. Drone sensors [from the table on SR4a p334] have Sensors with Signals from 2 to 4, meaning 3 to 5 including Improved Sensor Array [ISA]: a large drone with ISA has a Sensor range of 4km, greater than any sniper rifle in the game. [1650, if I'm not mistaken: 1500 + 10 percent from Extended Barrel.]
Simple. An Improved Sensor Array only raises the size/capacity of the Sensor package. I can agree that this includes the power/capacity to increase the Signal to that package to the next step. So a Large Drone gets Signal 5 (4km)... Not sure how I missed that particular bit, but it still does not change the scenmario. The Sensor will still not likely pick up a Competant Sniper.

Vehicles and emplacements have even longer ranges; many ground vehicles have Sensor ranges of 40km or more; any vehicle can have a Sensor range of 10km with Improved Sensor Array. So there are plenty of vehicle sensors, including drone sensors, with ranges greater than any sniper.
Yes, I know that. But how many of these are you going to see on the street, realistically. Vehicles like this stand out immensely. And even still. They will be unable to make the roll due to the massive penalties that can be ammassed when Sniping.
QUOTE
I'm not sure where you're getting these numbers from, either. Could you explain?
Let me try.
An internal Silencer on a Sniper Rifle has a base of -6
Electronic Firing is a -1
For Closer Ranges, Subsonic Rounds add another -2 (I would never allow these beyond Medium Range, personally, but by RAW, they are allowed)
Depending upon how your table rolls; -3 for Far/Distant Shot (or -1/-3/6 for Range Increment penalties), so up to -3 or -1/-3/-6 dependant upon Table.
Interfering Sight/odor/sounds -2
Active Looking (assuming right place and right time, does not help if you are looking/listening in wrong direction, or not at all) +3, otherwise an additional -2 for Distracted. I will break that out seperately.
Lets see.
For Sounds against a Threshold 2 (Silenced Fire), that would be a -9/12 for Hearing the shot, additional -5 if "Distracted" rather than Active looking (you lose the +3 and gain a -2)
For Sight against a Variable Threshold (lets say 3 for the Sniper, with an inherent -4 for Chameleon Coating); that would be -9/-12, with possible additional -5 if "Distracted" rather than active looking (Again, you lose the +3 and gain an additional -2)...
You will never smell the discharge at that range, so no roll...
Radar, at Rating 4 and Clearsight 4 will have 8 Dice with a Threshold of 5 for the Bullet (Micro), so not likely.
Drones cannot defeat those penalties, at extreme range, against a Sniper. Will not happen.
Sound: 10 Dice, -9 for lowest penalty is 1 Die (Threshold 2), Highest Penalty is going to reduce the Dronbe to no Dice.
Sight: 10 Dice, -9 for lowest penalty is 1 Die (Threshold Variable, Likely above 3), Highest Penalty is going to reduce the Drone to no Dice.
Ultrawideband Radar: 8 Dice vs Threshold of 5. Not likely, but has the best chance of detecting the bullet, though it will still be too late, and it will still not detect the Sniper, since he is out of the Range of the UWB, which is hard limited to 100 Meters.

Could you provide a page reference for this? My understanding is that Sensor ranges are determined by the table on SR4a p334, and not by the rating of any individual sensor or Sensor package.
They are. The table for Drones is Signal rating 2-4 (100 meters to 1km). Vehicles have a Signal Rating of 5 (4km), unless equipped with the Improved Sensor Array (raising it to 10km). A Large Vehicle Array stands out.
QUOTE
Exactly true: range is determined by size of the vehicle, plus ISA...
...but no, the Signal Rating of the device or drone is the range of the wireless transceiver itself [SR4a, p222]. That's my understanding: again, if you could hit me up with a page number explaining that Sensor range is equal to vehicle Signal, I'd appreciate that, too.
Signal Range for Sensor Scans based upon the Sensor Package Size
QUOTE
Each package has a sensor range that indicates the limits of the sensor’s reach (see the Signal Rating Table, p. 222), though some specific sensors have their own maximum ranges.
This is independant of their Signal Transceiver for broadcasting the data the sensor picks up. For most Sensors, this Device Rating is 3 (Electronics/Sensors). So, most Sensors can transmit to a range of 100 Meters. However, their scanning range is based upon the Package they are in (0 for an RFID (so 3 Meters) to 6 for a Large Vehicle Array, which only a VEHICLE CAN HAVE, for a Scan Range of 10km). I can agree with you that a Large Drone could indeed have a Base range of 4km, since it upgrades to a Vehicle Array in Size (so, Signal 5).
So, once again, most Drones will have Sensor Ranges of Rating 3-4. Yes, A LArge Drone can get to a 5, and a Vehicle can get to a 6.
Whew... Does this make any sense.
