Vehicle turrets, Confuzzled about the rules Options

[Crusher Bob]

Some back of the napkin calculations suggest the following:

Roll a number of dice = to rounds fired, TN 30.

assumptions as follows:

Beaten zone is 25 meters in radius (approximate area 2000 square meters)

A target area (ie, you) is 1/4th of a square meter, making for 8000 potential target areas...

Assuming the bullets are completely randomly distributed over the beaten zone, the chance you will be hit with any single bullet are approximately 1/8000.

The chance of getting a 30 on an exploding d6 is 1 in 7776 (close enough).

Test case:

Team of 4 is hiding in beaten zone.
100 rounds are fired, so there are

Chance of any 'single' team member to be hit 1-(1/7776)^100...

Around 1.3 %

Chance of at least one team member being hit:
(~.987)^4...

Around 5%

Changing the odds to a platoon of 40 guys...
Around a 40% chance of hitting at least one guy...
Not bad for only 100 rounds...

Now imagine that I'm firing a good 5000 rounds...

Just remember, the ONLY way you are allowed to do indirect MG fire is with a battletac system installed on 2 drones, a spotter drone, and the fireing drone. Also you need the battletac fire-direction data manager installed on the remote deck. Thats why you're allowed to do it, is you have computers made specifically for calculating out indirect fire equations installed telling it where to point the gun, and such.

I recall a story where a shooter was attempting to flush out a sniper.

The shooter only had an assault rifle and had no hope of hitting the sniper normally - too great a range on a flat trajectory. He ended up aiming high and raining the rounds down on the sniper's position from a high arc, with the aid of a spotter. No electronic aids necessary. Didn't actually hit, but certainly made the sniper withdraw from that position.

I don't see why you couldn't do the same with a MG for suppressive fire purposes as mentioned in this thread, battletac or no battletac.

Karma, for that situation to happen in shadowrun, they would be well outside the maximum range listed for a MG. Thusly, you can't do it because of the ranges involved.

When indirect fireing a MG with a drone, either you're firing it at them attempting to hit them through the barrier, or the drone and battletac computer systems can do the calculations required to make the vast majority of the rounds land on the target even if being fired at a large angle.
