Yes so we already have plans for this, the only reason they aren't in yet is because we wanted to focus player population into the major divisions first. Our plan is to have three special forces companies for each faction. Right now we are planning on having Delta Force, 75th Rangers, and Green Beret for the U.S. Army side, and Quds Force, Saebrin Unit, and Persian Marauders for the I.R. side.
We will most likely allow one specialty group in each major division, with jobs in-game to back it up.
NOTE: The three special forces companies I mentioned above will be separate from divisions, they will reside in their own corps and lead themselves independently.
