Low SP T1 sniping setup
High
6x 1400mm with various types of ammo, use named guns(which are cheaper than T1 in empire) and faction ammo then you'll do solid damage.
2x Large Nosferatu/Neutralizer/Remote Rep (Hull or Armor)
Mid
1x 100mn MicroWarpdrive I
2x Sensor Booster I
2x Tracking Computer I
Low
3x Gyrostabilizer I
1x Tracking Enhancer I
1x Power Diagnostic System I
1x Medium Armor Repairer I
With the advent of Revelations T2 snipers have been reduced to being more in line with T1 snipers as far as range and damage are concerned. This is a fairly standard sniper fitting, although the spare two highs are fairly modular, along with one of the Tracking Computers and the Medium Armor Reperair. Switch Medium Armor Repairer to a Small Armor Repairer and use a Reactor Control Unit if your fitting skills are bad.
High
6x 1400mm Howitzer Artillery II
2x Wildcard, NOS/neuts/Remote Reps
Mids
1x 100mn MWD
2x Sensor Booster II
2x Tracking Computer II
Lows
3x Gyrostabilizer II
1x Tracking Enhancer II
1x RCU(II if possible, so a large remote rep can be fitted)
1x Damage Control II
Drones
5x Warrior II
5x Medium Armor Maintenance Bot I
This fitting requires Advanced Weapon Upgrades IV or a t2 RCU (Failing that a PDS or 2nd RCU can be used in the wildcard lowslot).
If you can only use t1, then you do not need the RCU if you have Advanced Weapon Upgrades IV. In which case use the freed low slow as another 'Wildcard', or keep it to be able to fit NOS/remote reps in the 'Wildcard' Highs.
Fly around and shoot the primary, try not to die. Stay aligned, warp out if you get primaried, or if BoB drops a doomsday. Use the MWD to get out of bubbles, use the drones to drive off interceptors, try not to die. Most of the t2 fittings are pretty cheap now, so use t2 if you can. Fit guns you can afford to lose, and try not to lose them. Don't die, you're of no use to us if you're dead, soldier. PS: Don't die.
