This concern inevitably arises whenever the discussion of playable riflemen is raised. Some people fear that SB will immediately turn into Counterstrike or Battlefield.
I just don't see it happening:
1. We already have crewable LMGs in game and yet we do not see this type of behavior. This is mostly likely because....
2. The realistic nature of SB doesn't lend itself to rambo tactics - you will most likely be killed the second you rush at a tank or infantry squad.
3. I don't think this is something we'd see from the SB community - at least I've never seen it in the 10 years of play, among various MP groups. This goes back to #2, and the fact that this isn't the type of game.
I've seen plenty of players miss their target using an ATGM....a guided rocket. I think human nature would factor in, in some cases.
