Get your overall rank to Lieutenant
You have to get the mongoose mowdown acheivment by running over and killing a player on lone wolves ranked matches.
You have to find the shoulders in the shoulders in the section in halo reach
scout armor is only for looks
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!
You don't even need to finish marathon man to get the security shoulders. All you need is 750G in Halo 3.
Find the sculls and at some point Manofcool
for finishing the halo 3 campaign on heroic you unlock the E.V.A helmet, plus the shoulders and body plate for certain missions.
