First off...these are average kills for a single target, out of cover, with no funky rules. YMMV. Rapid fire isn't included, as I presumed everyone here could handle multiplying by two. All BS are assumed to be 3 unless the weapon only comes mounted on a platform that is always better, such as a hammerhead. Templates are listed on a per model under template. Simply multiply by the appropriate no of victims to get your casualty rate.

Effective BS Table:
TL BS2 = BS 3.33
TL BS3 = BS 4.5
TL BS4 = BS 5.33
TL BS5 = BS 5.83
Note that the biggest gain is going from TL BS 2 to BS 3. This only affects gun drones in our arsenal, but it's worth noting that a ML used to boost them instead of an equal number of FW with carbines is more efficient.
