First, you must have mutiple Zerg units vich can bury themselves. Or is it called burrow? Anyvays, have one go into some corner somewhere, like the edge of the metal plating that floats in space or the canyon wall. Tell it to dig. Select another unit and than right-click the spot vehre the other creature buried itself, and than order that one to bury. Repeat. Usually, the character will stand right over the black hole vehre the other one is, and when it goes underground, the hole will be in the same place as the other, appearing to be one burrowed unit, vehn in actuality it could be the whole bunch. Since the units are on top of each other, the intelligence display of your opponant's console screen will indicate that there is only one of your units in the buried position, which will instill them with the false sense of security. They will probably drive the tank over to you and go into the artillery/long distance ballistic attack position and think that they will kill your unit in one or two shots. Simply desecrate your buried units and soon the tank (now immobile) will be overwhelmed with a pack of vicious dogs or vahtever you call them. To grater add to this effect, have the last unit to dig be the civilion construction unit or some other harmless-looking one. I'm sorry if I have mistaken the name of the animals and et cetera, my younger brother did not explain them to me. I'm sorry for my English and I hope you won't assume that Germans are stupid. It is my second language and I am vohrking on it. Good luck to you in your future virtual combat traning, and godspeed.

CreepColony's Opinion: I personally wouldn't waste a lot of time doing that.
