Like the post said they are the two middle ones pictured and they are impact "drivers" not impact wrenches which have the anvil on it. They can be used with sockets and that is pretty much all i have ever used them for. You just need to buy the hex/anvil adapters. Under 10$ at home depot, lowes, or wherever store you go to.
