Best build orders for usa

[waqs]

1)against GLA is it best to build 2 dozers or 3 and use the 3rd to kill workers and prevent tunnels. Should you sell your CC.

2)against china,its a bit more straitforward. I make 2 dozers,sell CC but should my second dozer build barracks first or should it build 2nd supply depot?

Third dozer will effectively knock out flank tunnels for you, but it's not economical: you're losing $1000 and the ability to go dual supply, he's losing an extremely expendable worker and getting an opportunity to scrap up the inevitable vet-tech raid. Don't do it.

The only cost-effective way to stop early tunnels near you is to get 2 rangers in a nook asap and cruise around your base. Kill the workers. Then check if he boxed his supplies without a tunnel and maybe you can get a drop on his supply.

Always sell your CC if you're not helpless without radar. USA's intelligence is always good vs. the GLAs, but you'll be fine if you just get scout drones, check your flanks constantly, maybe get a few comanches in the air.

Against China, USA can go forward rax and try to suppress China's middle build, or they could play it safer and go for a rear base with dual supply. I'd recommend the latter if you're a lowly player like me, but altogether, you should make sure never to make a third dozer in 10k matches (unless the map is gigantic) If you're USAF, go 1 supply and fast-tech to the carpet bomber and you'll rape any non-infantry, still with just two dozers.

I always get both my supplies up first as USA against China. I'm not sure if that's the right thing to do. Then I make Rax/WF between them and start the wubvees comin'.

Its not the only economical way, though it is my preference. Other alternatives are to take the dozer that finishes your first supply and chinook drop that (about the same speed as ranger drop and cheaper, but it slows your BO and the worker might escape to a bunker) or take your other dozer and instead of building a second supply check that flank for tunnels first, then come back.

Yeah, unless you plan on MD or Pat dropping. The bigger question is whether to build a rax first or WF (I usually get the WF because it takes longer to build, so starting the WF first means they will finish at about the same time).

I usually go Rax 1st, as I can get out rangers/MDs to stop workers, Hunt Trucks, kill Drops, etc.
