Well, with the CA stratagems, you have a unit with 2 dice, and the 2 important units have re-rolls on the cult chart, if you 2nd important unit doesnt make it, spend 1 more CP to re ambush them next turn.
With +1 atk, +2str on your key unit (Either Aberrants or Purestrain) and your key unit 2 dice re-roll, with re-roll hits of 1, you only need 1 key unit to get into 2-3 units to win the game. Genestealers will kill 3 units on the charge, 100 S6 attacks with AP is insane, I've seen Aberrants kill 2 units on 1 charge.
You just need to buff the right unit at the right time, then you have another 40-50 basically shotgun, CCW +1 atk or str Guardsmen as shields for your other characters and chaff clearing.
If one of you 10man Shotgun units can shoot twice, it will easily kill equal points in any other chaff and more so. 80 total shots, at least some at S4, most will be S3 tho, but thats still 40 hits from a 50pt unit.
I know it doesnt sound like much, but when you add the powers (Buff stacking) its stupid insane.
I now im repeating myself, but its a total of, +2str, +1 attack, no overwatch, make them shoot their own unit, re-roll hits, adding dice to ambush table and re-rolls. And you skip turn 1 (For many missions and ITC you are denying points)
