Being a soldier was the only way for a member of the working class, or the children of soldiers to become a citizen. You could be discharged in one of three ways: ignominiosa, because of bad discipline; causaria, because of health problems; or honesta, for completing service to the satisfaction of your superiors. This last was the only way to obtain citizenship, except to be the child of two citizens. A soldier with honesta was given a piece of land and an amount of money somewhere in between 3000 and 8250 denariii, more if the soldier was a centurion. The primus pilus was given enough money to retire and live well for the rest of his life.
