This is simply a guide on how to counter a specific type of unit, if you don't know the best ways.
Feel free to object or add something.
Romans Missles own these guys (black queens included) If it's early in the game, break out air units, preferably phantoms. Tanks also do a good job. (Romans have weak range and low unit damage)
Scouts Sakata MII wipe them easily. Marines also do a good job in masses.
Phantoms Sakata MII, or scouts/black queens. Missles work too.
Sakata MII Any ground unit will take care of it, hover tanks are the best.
Sakata Spider Massed tanks can kill it before it gets in range, air units also do a good job.
Gladiators Hover tanks. Period.
Marines Tanks are best for this job. Black Queens and missles are also fine.
Chronite Tank Any air unit will kill this, because they are so slow. Missles will take them out too.
Snipers Get any stronger unit within range and that'll do it. Missles work just fine as well.
Groditz Missles, tanks, phantoms are also stronger than groditz in forms of machine gun fire. Hover tanks Phantoms work wonder here. Black Queens Strongest counter is probably Sakata MII or Gladiators.
Misc Tips -
1. Missles will kill the following in one hit: Romans, scouts, phantoms, sakata spiders, marines, chronite tanks, snipers and groditz.
2. Don't use forge/forge.
3. Armories are actually cheaper resource structures than banks and generators because it doesn't require upgrading. (and provide more than tier-1 resource structures)
tell me when you build a large mass of hover tanks and a black queen, wasting all your resources and ill make sure to build a couple sakatas and a couple phantoms.
Pretty much everything. If you get ANYTHING, except a sniper perhaps, in range of the Pride...it'll die, cause it just doesn't have enough power to kill anything.
Saint-->The normal anti-air, sakatas. Or mass scouts, but it does have splash i believe. A queen will tie.
Farsniper--> Pride or romans...or whatever you normally use for anti-sniper (saint works wellish)
