Learn What Micro Is
There are two parts to Starcraft 2, macro and micro. Macro is what we’ve discussed about earning and spending money, micro is how you control your army during battles, and it can often cost you a close game.
A lot of micro is pretty advanced tactics, but there are some basic rules you can follow, like moving back injured units so they don’t die, letting your other ones keep fighting. Also it has to do with positioning, like not engaging in little choke points and things like that. It also has to do with spell casting where things like force fields, fungal growth and psionic storm have to be used precisely to be effective.
