This tip is recommended for fans of terran ground-based attack. This tip will definately take you a long time to prepare, a lot of resources, and quite a bit of mromanagement.

Force Composition:

12 tanks, 3-4 groups of marines, 12 wraiths (fully researched) 3-4 science vessel ,12 ghost (fully researched), and 3-4 nukes. Valkirie, medic, and charon booster upgrade if in Brood War.

As i say this takes a long time to prepare. But using this force I defeat my opponent in almost any situation.

Tactic:

-Against mass ground units (mass hydra/ dragoon/ marine?) Try to set up siege tanks before they charge at you. EMP the place (i hate defilers and high templars, and it removes protoss shield). Use the marine to charge, but dont stim pack. You want to keep them away from tanks as long as possible. If there's no detector, use wraith to attack 2-3 line of your oppenent's unit. This will cause his troop to start going all over the place, and inconsistent. From now, if he still have a bunch more unit, sent a ghost over and nuke. His 2-3 line should block rest of his army away unless your oppenent order again. When it goes kaboom! it's over, replace you dead marines, regroup and keep going.

Tips against mass hydra: Irradiate will have devasting result. Tips against mass Dragoons: Lock down the first line, then nuke. Tips against marines: Use ghost in battle, irradiate.

-Against fleets of capital ships (battle cruise/ carrier). ALWAYS lock down detectors first, and arbiter if toss. Then EMP the place (decloack enemy wraith, reduce shield, drain energy). Pull rest of ur force away except wraith and ghosts. Lock down the ships, get wraith in and wreck havoc. If you're in a hurry, nuke will do the same.

-Against mass zerg airforce (mutalisk/guardian). Irradiate guardian first, then overlord, then muta. Even better, irradiate your air unit and charge right up to them (put defence matrix for protection). Pull tanks back, take out remaining detectors. Bring your wraith and ghost wraith go for guardian, ghost go for muta. Now marines can also join the carnage too. But if all fails, nuke fix anything (defence matrix the ghost, and start the nuke as soons as your force is in bad shape) Some goliah can also be good help in this scenario. And if you are in brood war, valkriu and charon booster is a must.

Tips: again,if you see any units with special abilities, EMP or kill.

-Against Terran supply block/ siege defence. There are many ways. Nuke the ground b4 them so your out of tank's range. Or defence matrix your tanks and set them up right b4 the defence. If there's no detector, your ghost can lock down tank and wraith can take it out. Even better, you can bombard their coast defence with tank on the other coast, then bring in wraith for sugical strike.

Some other useful tips: -when enemy defence force is destroy, but reiforcemnet is on the way. Line up several nukes loosely together around his production building, This will usually blow up everythink in the screen. -Defence matrixed ghost have large potential. -Always take out detectors first. -Against zerg, when oppenent's force annilated. Hunt down overlords with wraith and ghost. -Always number your unit types.

This tactic, if used carefully can guareenty victory. But since alot micormangement is involved, it doesn't suit alot of people.

CreepColony's Opinion: This is a good strategy, but like it says, requires a lot of micromanagement. Also, since this is a mostly ground bass attack, this will probably only be effective on a map with lotsa room.
