US Army Special Forces are a unit that belongs in the Special Operations Forces (SOF) which comprise of several special units from Army, Navy, Air Force and Marines.

In the SOF, since you've mentioned Army units, you're mostly left with the Special Forces and Ranger units. The SF pics that I've seen, they wore a wide range of gear from chest harness to armour vest. If you want to be like a Ranger, just make sure that the gear comes in Ranger green. You're pretty safe if you choose something that is made by Eagle. Lot's of sites will have specific threads on these units so that you can get a better idea of what you like.
