The Battlemaster Legion of Tuchanka was a branch of the Tuchanka State Union. It served as the military force of the krogan species. The legion grows and trains pure-krogan soldiers to fight in their armies. They also send Blood Pack teams out into the galaxy to retrieve vorcha and varren which are then brought into the fold of the military. The Battlemaster Legion trains more than 50 Battlemasters a month and more than 50,000 every six months. The Battlemaster Legion has also created a large naval force after the sudden economic burst. At it's peak, the Battlemaster Legion rivals the old krogan armies of the krogan rebellion.
