I was thinking about ToS+Precision for a fully anti-tank unit. I can confirm that Blaster reavers works pretty good with ToS, and you can charge some.veichles too, wounding on 4+ (vs T7) and pushing some wounds with ap-2. As always, Drukhari are an amry where more units needs to works together for anything, and those units seems nice to strip.some wounds on veichles helping other Dissies/flyers etc.
Of course bring some flyers in that detatchment too. ToS on Void are great
