I understand the formulas posted on the wiki for the robbery operations pretty well, but the others listed on the wiki are less clear. For example, the gains per thief for nightstrike is listed as 90%. Does this mean that, disregarding the other factors, thieves sent * .9 = soldiers killed? I don't think that's right. It would also seem to indicate that you need about 10x as many thieves to kill 1 troop in a nightstrike as to steal a horse. Though I've never actually stolen horses, this doesn't seem correct.

Also, nightstrike kills soldiers, specs, and elites at different rates. Does anyone know what that breakdown is?
