How do i get advantage from using Guerrillas?

[juvilado]

Hi, i've been playing for a while and still don't catch the point of the guerrillas. They are supossed to be a good unit (from what it is said in the forum), but i don't know how to use them properly i think. Can you give me some advices and/or explain in what do they excel?

In addition, for hiding, should the guerrilas have the antisupply option set to "off"?

If anti supply works you want it on it interdicts the enemies supply flow.
