Assault can heal and revive teammates. Recon has a sniper-rifle. Engineer can repair vehicles, and gets a rocket-launcher and proximity mines. But Support, from what little I've played it, seems to just have extra ammo, which is not nearly as useful as every other class's specials.
What special things does Support do? How do you effectively play as Support?

The view of the classes you present in the question is way to simplistic.
Support
And BTW you say just "Recon has a sniper-rifle", which is big understatement.
Recon
