There has been alot of talk and moaning regarding the perceived notion of having only 4 units under your command with no ability to expand this number. Helios today clarified the information presented in the UGO preview and the public view generated from the EGO preview.

Hi all,

I just wanted to clarify that in Operation Flashpoint: Dragon Rising the player will be able to command not just the one 4 man fireteam as was said in the UGO preview, but as a squad leader multiple fireteams.
