The only way to unlock the security armor is to get 1000 gamer score for Halo 3, this means you need to unlock every single achievement.
Accualy, you must beat certain levels of the game on Legendary difficulty to unlock the armor. If you get all of the gamer score, you get the katana. It is a sword that goes on your character back. Even though you cant use it, it looks pretty cool. Also, the security shoulder might glitch. This means that once you unlock them you must wear them FOREVER. If you don't, they might disappear. This happened to me. :(
You don't even need to finish marathon man to get the security shoulders. All you need is 750G in Halo 3.
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!
Then you won't have security shoulders. You must continue to earn achievements to unlock them. The security shoulders are linked to the Metagame achievements, so make sure you have them.
Depends on your definition of cool. It is an opinion.
in the achievement were in for some chop on halo 3 you do not get scout shoulders, sorry
To get the security helmet you need to have over 1000 gamer scorer from halo and 50 achievements.
when you activate them all you get the achievement called Marathon Man. It should unlock the armor called Security Shoulders
You have to find the shoulders in the shoulders in the section in halo reach
well I got my security shoulders when I reached the gamescore of 850. That sucks I know but I got Katana and security helmet at the same time at the gamescore of 980...pretty glitchy eh? My friend got them when he reached 450. Security shoulders are known to be really glitchy :D

Technically no, the only way to wear armor in halo 3 that you can wear in reach is some of the basic armor that was already available but the new pieces of armor such as the security shoulders, sapper chest with robot arm, an gungir helmet are only available in Reach.
You have to get 1,000 gamer score on Halo 3.
