There were a total of two main divisions that existed within the Magus Alliance Military; the Knight Brigade and the Magus Brigade. Both have their own function toward protecting the human universe.
With a ratio of 1000 to 1 in number of members, the Knight Brigade had dozens of ranks and titles within its body. Meanwhile, their counterpart - the Magus Brigade - only had three of such things.
The Magus Alliance Military defined the division of their combatants into three terms: squad, platoon, and legion.
Squad is the term for a unit consisting of five to thirty people and is led by a Captain.
Platoon is the term for a unit consisting of three to ten squads, up to three hundred people and is led by a Commander.
Legion is the term for a unit consisting of three to ten platoons, up to one thousand people and is led by a Supreme Commander.
