lol a lot of time would have been saved if some of you bothered to read First Strikes.
blitzkrieg,
For all intents and purposes Drill 3 is the same as Drill 2. IMO Drill 3 is the problem with the drill line because it's less than half as good as Drill 4 and only as good as Drill 2. In PIG I increased it to 3 first strike chances instead of 2.
Anyway, as for that lovely CR3 cannon, drill will improve its survivability, if that's what you value. If you are expecting it to die at any moment, I'd go with barrage.
