After you reach SR 50 in Halo 4 you get to choose a specalization such as Wetwork, Operator, Stalker, etc and these levels go through from 1 – 10. Once you have your chosen unlock, do they grant you any special abilities or is it just armor? I have the full set of Venator armour with a fairly distinctive visor and would like to keep it unless there are other benefits.
It's quite overwhelming the amount of customization and unlocks in Halo: 4.

Yes the specializations unlock unique bonus armor mods. They also get an armor, armor variant, weapon skin, and a set of visors.
The armor mods provide the following abilities.
