I think we should make a Ranger's faction...
Joining
To join the NCR Rangers faction, you need to talk to Elise.
Before join you need to do some quest like a: Save ranger in V13.Ranger was been trapped by slavers they want ransom,but rangers will never deal with slavers,so your quest is go to V13 and kill all slavers and save ranger.
Then come back to NCR talk to Elise and become a NCR Ranger.

In last quest you should gain a NCR Ranger Combat armor,this armor is pretty nice and rare,so they are allways in base and they are begin to rust there for ever.This armor is not so good as BA so i think it will be good to gain NCR Armor this way.Quest should be something hard for time to do like kill 200 Slavers in wasteland.
There should be added NCR Rangers faction terminal where you can leave (Resign).
