I think I'm a little unclear as to what the numbers on the weapons table represent. I'm under the impression that the numbers represent average wounds? but now looking back on my math it does not seem to work?

Can anyone clarify what the stock formulas are for doing these sorts of calculations?

The "ppk" numbers represent the "points per wound" essentially the "price" (in points) of a single wound against the indicated target in one round of shooting. 10 Gun Drones shooting at T3/6+ should deal 8.64 total wounds worth of damage. As 10 Gun Drones cost 80 points, this is 9.26 points per wound. This is for one turn of shooting only of course- if the Gun Drones deal this damage across multiple turns their points-per-wound efficiency increases dramatically of course.

If anyone's curious I've now tried out the solo Devilfish unit in a few games, and at least by itself it's really not that useful. However, I have found that Gun Drones accompanying battlesuits are a fantastic way to get anti-infantry firepower to the battlefield. At the moment I think the "perfect" Gun Drone deployment method might be a pair of XV9s in separate units. Let's look at some numbers:

**Group 1: 260 points**

Elites - XV9 w/ 2x DBBC, Drone Controller; 4x Gun Drones (130)

Elites - XV9 w/ 2x DBBC, Drone Controller; 4x Gun Drones (130)

**Group 2: 257 points**

HQ - Cadre Fireblade w/ Markerlight (42)

Dedicated Transport - Devilfish w/ Burst Cannon, 2x Gun Drones (127)

Fast Attack - 5x Gun Drones (40)

Fast Attack - 6x Gun Drones (48)

Here's the math against a few different targets. I understand that there are multiple units with different BS in Group 2, that's factored into my calculations.

**vs. GEQ:**

Group 1: 48 shots > 32 hits > 21.3 wounds > 14.2 kills

Group 2: 85 shots > 32.5 hits > 21.67 wounds > 14.4 kills

**vs. MEQ:**

Group 1: 48 shots > 32 hits > 21.3 wounds > 7.1 kills

Group 2: 85 shots > 32.5 hits > 21.67 wounds > 7.2 kills

The Devilfish/Gun Drone unit absolutely pales in comparison to the XV9s not only in terms of firepower, but also usability (the Gun Drones can only really fire on turn 2) and deployability (the XV9s can deep strike). Since the Gun Drones only net an average of 0.2 more kills for only 3 points cheaper, I'd say that the XV9s are better.

I'm not recommending that mech Tau players abandon Devilfish lists for XV9s, but just that the mechanized Drone loadout isn't quite as effective as it seems.
