Less is More Mastery Achievement - Starcraft 2 Nova Covert Ops
66Small task force achievement here. I think the most important thing to do to make life easier for this achievement is to grab two early garrisons. The reaper one to the north of the base is almost free to take and will help a lot with the attacks on the top left part of the base.
Nukes are great to use since they will compensate for the lack of army and do not cost money or count towards army supply. Building one extra ghost academy early and another shortly after will give you the nuclear firepower needed to clear this mission out before the attacks get too heavy to hold with 25 army supply (guardians/ultras).
Relevant tech choices: Jetpack tanks, Stim marines. Other stuff doesn't really matter.
