Terran has many strategies that will crush the Protoss especially later on in the game. Pay a lot of attention to the beginning and plan for a rush.

- Zealots do OK against marines; Dragoons do OK against Vultures and pretty good against Firebats.

- If attacked by cloaked Wraiths and you don't have observers, then Psi. Storm the region you think the Wraiths are present. Look at where its missles are being fired from.

- Don't waste Carriers against Battle cruisers or Missle Turrets. It'll just be as waste of resources as well as efforts to build the carriers and interceptors.

- Once you're capable of making Observers, then have at least one of them in every single attack force! Terrans have many units that can cloak and the Observers can spot the cloaked units without being spotted.

- Keep in mind that non-upgraded Siege Tanks are about as strong as non-upgraded Dragoons.

- Use Reavers to take out Missle Turrets and Bunkers. You can try using carriers to take out Bunkers if there are no other nearby threats to the carriers. Once the bunker blows, then retreat or send your troops in.
