A security unit on patrol has got to deal with all sorts of potentially nasty things:
Mages, heavily armoured drones/spirits, trolls tanks on the rampage, threats that are normally invisible, stuff solely astral, and a whole host of other nasty critters.

So what would a small patrol unit look like that can cover everything but not break the bank?

A patrol will consist of 3 units:

Security Guard (Ork, built with around 250 CP to make sure he's not too good at the job)
Body 5
Agility 3(4)
Reaction 3(4)
Strength 4(5)
Charisma 2
Intuition 3
Logic 2
Willpower 3

Athletics (Group) 2

Perception 3 (visual)
Clubs 1 (stun baton)
Long Arms 2 (battle rifles)
Thrown Weapons 1

Dodge 2 (ranged)
Etiquette 2 (corporate)
Con 1 (sense motive)
Intimidation 2

Infiltration 2

Wired I, muscle replacement 1

He's the face of the group, there to notice stuff (8 dice to see stuff), talk to people, and he has some chance of resisting a con or an intimidation attempt.

Since he is also the most accurate of the 3 (10 dice to shoot with a smartlink) he gets the anti drone/spirit gun.

Since the BBB doesn't offer a gun that does what we want, we'll have to make on up:

Battle Rifle (RL equivalents: FN-FAL, M14, G3, etc)
Skill: Long arms
Range category: Sport Rifle
Damage 7(-2)
Modes: SA only
Feed: 20 round detachable box magazine
Features: RC (1) from recoil pad, smartlink
Cost: ~1250Y

Loading APDS in the rifle gets you a damage of 7(-6), and you can threaten stuff with 13+ points of hardened armor, so you can damage a stock steel lynx or a force 6 spirit.

He also gets an armored jacket + helmet (armor 9/8 total), with some fire proofing
Goggles with smart link + ultrasound
Earphones with +2 hearing enhancement (so he rolls 8 dice to hear stuff too)
A stun baton
Some thermal smoke and flashbang grenades.
Biomonitor

Typical combat response
Take cover, direct the dogs to fire, and call in a contact report. If there is evidence of magic, he'll use a free action to set off one of the thermal smoke grenades he is carrying and switch to ultrasound. Concentrate fire on anything picked out by the hellhound, or at heavily armored targets, as appropriate.

Trained Hellhound
Wears armor that provides around 5/3 armor, plus radio and biomonitor.

The hellhound has astral perception, letting it spot spirits, invisible guys, etc. It is well trained enough to bark when it sees something. It will also breathe fire at any magically active guys as a first choice. Note that the rest of the security force will tend to concentrate fire on anyone who is scorched looking, on the assumption that they are mages.

Typical combat response:
Observe targets in detail, looking for any that are magically active. Give bark code identifying that you have spotted a [magic threat type] and breathe fire at the greatest threat (by highest magic rating). If don't see anything magically active, just breathe fire at some random guy.

Doberman drone
Stock Doberman with white knight LMG (loading regular rounds)
As the cheapest thing in the patrol, the doberman is there to take the fire.
Normally directed by voice from the security guard and running in autistic mode to prevent hacking. If the guard it's following becomes incapacitated (guards biomonitor will broadcast), it activates wireless to get directions.

Typical combat response:
With only 6 dice to shoot something, the Doberman can't really be relied on to hit most things, so it will be using the spray and pray rules, so that it doesn't actually have to roll to hit. it'll just keep putting 10 rounds into the combat area every pass and hope to distract the other side. Plus all this fire will tend to make the other guys concentrate fire on it, protecting the other 2 units in the patrol.

Comments?

Just some nitpicking: If the drone runs in autistic mode and only accepts voice commands you have two problems.
First: Range will be an issue + silence spell/high background noise screws you over.
Second: How can the drone recieve the biomonitor broadcast when its wireless is turned off?

The partol operates in close proximity to each other, is things are so loud that you can't shout at each other then you probably have other problems to deal with.

The drone won't accept wireless command, that doesn't mean it doesn't listen. A more in depth description might go something like: At the start of each partol/shift/whatever, the drone and the guard check in. A random number is generated at that time for the guards biomonitor to broadcast to to activate the drones ability to accept wireless commands. Unless the drone receives the random number, it won't do anything for any wireless commands it receives.

If something goes wrong with the system, you plug a wire into the drones maintenance port and fix it.

But that implies it could be hacked by spoofing a wrong biomonitor signal as the drone is able to recieve commands (which it won't accept unless you make it to, and that is what exploit is all about).

Just to note that I like the general setup of guard + critter + drones, I'm just getting a bit itchy when it comes to wireless enabled, but unhackable units.

If you were willing to convert to Frank's Matrix rules, it wouldn't need to be set up like that. But the default stance for the standard matrix rules is to opt out of the Matrix all-together. If I just assumed that the drone was actually as smart a well trained dog, it wouldn't need wireless connectivity at all. But I'm assuming that the drone really isn't, so will need pretty regular human oversight.

So, still hackable with Spoof and the like.

Edit: Too many tabs.

Then the drone simply won't accept wireless commands at all, and you have to pay for a smarter drone pilot. Depending on how high a pilot rating you feel is needed for the drone to operate by itself (and Pilot 3 may be enough), you may be better of adding a second security guard instead of a drone, since the high level pilot can get pretty expensive. In that case, give the guards underbarrel GLs with flash bang for the area supression role. and get them heavy weapons (grenade launchers) 1.

Wireless enable the drone, and put the Smartlink with Safe Targeting in. This way if your hacker takes over the drone, it still won't be able to target security guards. The hacker will take longer to locate the section with "safe" rfid's, which is of course encrypted and data bombed.

Hack in (Admin Access only for Safe Targeting modification) Extended Threshold 9 Min on fast hack (Firewall 3 + Admin 6).
----Running Min Software as well, so Analyze 3 + Firewall 3 = 6 Dice on extended Analyze to break Stealth.
Analyze System to find Safe Targeting Information (Variable Threshold, we'll say 3 in that the Firewall is what keeps it hidden)
Analyze File (To Realize its Data Bombed.. Decrypting without defusing results in 3 Matrix Damage, and alerts triggered)
Disarm Bomb (Threshold 3 (or 6? I don't have book on me) NOT extended, Failure results in 3 Matrix Damage, and alerts triggered)
Decrypt File (Encrypt 3, Extended Threshold 6)
Edit File (To Remove guards, or add teammates.. whatever they have free reign now)

So this took 6 passes minimum, granted they can do it in less... But the bomb goes off and they have Network security on 'em.

Using base software on the drone, and purchasing Analyze, Encrypt and Databomb. Only one of these is an actual hacking program.
And Safe-Targeting is pretty much a must on any weapon that isn't going to be controlled by a Metahuman mind.
