It's too hard looking for that tiny little red dot. So don't, don't use your vision at all. Use your ears, after moving your main army out of the way. Use base cam or camera locations to cycle your bases. When you hear the tell tale whoosh sound pull workers. (In the video I launch the nuke. So I can hear it launch. If the enemy had launched the nuke I wouldn't hear that sound until my camera were over the area). If you're wearing headphones and are one base to the left of the dot you will hear it only in the left ear. If your camera is one base off to the right you will only hear it in your right ear. The base targeted will sound in both ears. This aplies to random locations on the map as well. This is extremely effective, the faster u can cycle bases the quicker you'll be able to pull workers..
