Being a terrorist faction doesn't exclude RP, in some ways it liberates it. The SCRA are political extremist with a self righteous attitude, we perceive ourselfs in character as the saviours of humanity here to liberate the misguided from their Alliance oppressors. But we're also a smaller force, and that limits the combat styles that would prevail.
Likewise, if you go into the history of the Coalition during the war in Sol you'll find them to be brutal, the opening sequence of Starlancer features the Coalition massacring the survivors of the French and Italians fleets even. Simply because ruthless violence is a large part of the cultural and political demographic shouldn't be considered as a clause stating that they can do nothing but PvP if their ID allows that, give a little credit to the faction members.
