Yes, there is a Security armor in Halo 3, Only the head and shoulders are unlockable.To get the head, you need the gamerscore in Halo 3 to be 1000g/1000g. And for the shoulders, the gamerscore is variable from 700-800 for some reason. (Note: If you get the shoulders, there is a glitch that makes you lose them when you earn them, but don't worry, they return back.)I hope this is useful!
The only way to get all the armor is by completeing the achivement or task online to get that sertain permutation.
You have the newer achievements, you need 900 from the old achievements then it will never glitch up, same with katana and security helm.
you have to get 49+ acheivments
