Interesting uses for Units

The problem with using mules to repair though is that you lose a lot of minerals using them like that.

If you are already well saturated on your bases, a mule, which can mine a mineral patch that is already being mined by an scv, is worth a ton more than an scv even though they repair at the same rate.

And of course scvs with your army means you can build turrets and stuff.

Still, you can't always have scvs around even with good preparation, and in certain situations, it might be well worth it to call down mules for repair if it ends up being the key to holding a line or saving some very important units/structures.

Remember mules also still have 60hp and may even be used to body block in a really sticky situation.
