I remember SF to have one thing no other type of unit has: a special skill. (hence Special Forces).
Every SF center difers from each other in this special skill, which can be something like a boost in scaling walls, defending or attacking, traveling, morale etc.
Vita or anaris should be able to confirm or deny this and also be able to specify what kind of skills are possible if i am correct here.
They are not visible and have to be discovered by trying these units out.
Unfortunately if anyone ever discovers it it is forgotten just as easy as it is difficult to figure it out
A small description box for each RC could permanently solve this and also add the opportunity for giving otherr(normal) RC's more character.
