Starcraft – How should I use Locations

I don't think there is a way to do exactly what you describe. If I am wrong, I would love to know about it!

The second best thing I can find is to set a waypoint to follow a unit in your main attack group. To do this, select your production buildings, find a unit that isn't likely to die anytime soon, and right click that unit. New units being produced will follow your main group, and will attack nearby enemies and such.

However, they still won't be in the actual control group, so you can't easily use their spells and whatnot. In order to set that up, the easiest way I've found is to select the units as they're walking toward your group (it's good to listen for "construction finished" sound bites and hit Space) and then press Shift+3 to include them in the original group.

Two things to watch out for:

1. Units heading toward waypoints are using the "Move" command and will not attack stuff en route.
2. If the unit you are following is destroyed, the waypoint will end up wherever it was when it was destroyed. If this is right at the front of the enemy base, that's bad.

Once again forgive me for the quality of my response I'm on the road till Monday.

I discussed in another question why I feel using drones to defend is a legitimate strategy. And I discussed how you need to use your drones to counter a rush. So I'm guessing you're looking for specific micro-ing techniques for using drones, and not a discussion for stopping rushes, as that's kind of been discussed to death.

Using Drones is a lot like using Zerglings they're both Melee units (a rare commodity in SC2), so they both rely on surrounding your opponent for victory. This means the standard sorts of rules: Don't engage near buildings, Move to surround before attacking, Don't focus fire, etc.

So let's focus on the Drone specific techniques:

• Attack Ground, not units (A then left click the ground). If you tell Drones to attack ground (instead of specific units) then they won't laze around after killing their target
• F1 will select any idle workers if you are microing. CtrlF1 will select all idle workers so you can Attack Ground again.
• Box all your units and add them to a control group. This will make it easier for you to send them all back to work when the battle is done.
• Micro the stragglers. Because Drones are Melee, it is possible that not all will be able to attack at a given time. If some are caught behind others, micro them around behind to help your surround (or back to work).
