Support is the ammo guy, right? Yup! Support can also do a verity of other things, and using those other things separates the good players from the great players.
Most of this skill actually comes down to what gun you are using, and how well you as a support player are fixing the ranging problem in your squad. If you have a medic and two recons, they need someone with medium range capabilities. What about if they need a building clearer? Shotgun baby!
