Gunery Sgt. Buck

Gunery Sgt. Buck is an ODST. He appears only in New Alexandria when you have to escort him. But you don't always have to escort him. He is not unique in any way and he is no differant than an ordinary ODST. He has an Assault Rifle. His firefight voice is in the armory and thats pretty much it. He appears more in Halo 3: ODST where there are no Spartans.
