The Fire caste are professional soldiers. In some ways, their training regimen begins moments after their birth, for the great communes are fully given over to raising the best soldiers and nothing else. Discipline, fitness, hard work and following orders are drilled into the growing warriors. It is customary for teams to be raised and trained together, allowing the troops to form strong connections - a comradeship-in-arms that will serve them well no matter where in the Tau Empire they are sent off to fight.
