Later when your defense is set up you can go for Battle labs and get your self some uber units for base protection when your main force destroys enemy base.
Another very nice way to use spyes is to infaltrate the power plant right before assult i usualy take out an entire AL base without any casulties with just 10 kirovs and some phoenixes initialy sending some bio fighters IF they have a stockpile of anti air units somewere.
FL is a bit trickeier to kill just because power is off and aa guns dont do anythign but devastators stil kick ass but can be easyer sometimes since tehy tend to leave nuke trucks in there base.
NEXUS is hardest AI to kill since 3 of tehre tanks shoot air and hack towers take over ur units lol even without power his base is protected ...not a problem if u have secret units tho
