Never really seen the point of deploying SO's tbh, if I roll CO I'll usually end up sending my XO planetside as my field adviser and so the marines have a higher leader they can rally on. But then again plenty of SO's don't really contribute much tbh (not to say that their aren't fantastic SO players who add lots to the round for both their squad and fellow CiCers), so I could see how sending down redundant officers to the meatgrinder could be more benefical than having them look through helmet cams.
I get sad though if im all alone in the CiC, and we have IO's now as a dedicated groundside officer class. Maybe we ought to add more for the SO's to do shipside (Like things other than just SOing?).
