First of all, that was an AWESOME writeup, Celtibero, kudos! I greatly enjoyed the "We make the dots conNET!" pun

Agreed; I'm capable of throwing FA fire from an Ares Alpha with the option of launching some flash-bangs from one drone, and I've got a Crokett EBR loaded with APDS rounds on the other, so I've got long range fire support covered, but I'm by no means a front line-combatant as my drones are apparently made out of paper mache, especially under the Run & Gun rules.
My aim (heh!) is to hover the sniper drone at long range (i.e. beyond the range of most normal weapons, so at around 300 meters or so, high up in the air), and have the drone take one Initiative Pass worth of Take Aim actions (once to reduce range penalties, once to increase accuracy (to 9) and 1 dice to the dice pool (wireless smartguns!) and then fire at whatever is attacking the team. I'm hoping the GM will allow me to fire through barriers using the camera feeds from my recon drones, which will be shadowing the team, and/or other team members video feeds, at a penalty of course, if it's impractical to take the drones inside somewhere.
The Ares Alpha drone is the most likely to actually accompany the team if they go in somewhere, as I can lay down some heavy suppressive fire with it to keep the mooks behind cover, and/or fire off the occasional grenade.
Spirits are tough, no doubt about it. But isn't that what we have two magicians for?

The good news is, I'm a pretty good shot with drones and vehicles, so if our resident decker can get me an account on defensive emplacements I can easily turn those on the enemy too. I'm rolling Gunnery 6 + Logic 7 + Hot-Sim 2 + Rigger Command Console 1 + Vehicle Control Rig 3 = 19 dice (-2 if Running Silent - 2 if operating on a different grid).
For my own Smartgun equipped weapons, it's the same as the above but +2 for Smartgun and +2 for Specialization with Ballistic weapons, but probably at least -1 for range. All in all, around 20 dice on the attack, and I might be able to get a surprise shot or two in by moving the drones around to ensure they are kept out of the line of fire (i.e. aim one IP, fire one IP, move and hide one IP, then repeat) and don't get shot down.
[EDIT]
With Hardened Armor, it's my understanding that a Force 6 Spirit is going to be a tough nut to crack, even with a surprise attack from my sniper drone.
If I get to roll my full 23 dice, representing my maximum damage potential, that's a mathematical average of 7.67 successes;
If the spirit gets to roll to avoid the attack, they roll anywhere from REA 5 + INT 6 = 11 dice (Spirit of Earth) to REA 10 + INT 6 = 16 dice, representing a mathematical average 3.67 and 5.33, respectively. This reduces my net hits to anywhere from 4 to 2.33, respectively.
The good news is that as long as I hit (i.e. one net hit) I'll always punch through their hardened armor due to the base (12+ minimum 1)P -7AP of the Crockett EBR with APDS. A Force 6 Spirit has a Hardened Armor value of 12 against normal attacks, which is reduced to 5 when hit by the sniper rounds, and the resist with their BOD 6 + Hardened Armor 5 = 3.67 + (5/2 rounded up = 3 autohits) = 6.67 soak.
On average, then, as long as I hit the spirit I'll do at least 6.33 boxes of damage, which isn't bad for a drone operator. The added bonus is that Spirits have range increments of F meters, so at least I'll be safe from retaliation for a while, since my drones are pretty fast. My best bet is to try and draw any spirits present away from the team and harass them with alternating drones from beyond range
