Re: Colossus Armor - Light - Human
I got it on my first playthrough from Alliance Requisition Officer. Guess I got REALLY lucky considering it was hard to find any higher rank Light armor for humans AND quarians. (by the time I got to the end game, the best Tali had was Phoenix VIII; couldn't find anything better even from shops).
But human, krogan and turian medium/heavy armor were very common.
