The Third Cohort of the Twelfth Legion is a moderately good cohort. One of the known centurions in the cohort is Hank. Not much is known about the Third Cohort except that they won the Roman War Games against the First Cohort and Second Cohort.
A Legion was made of ten cohorts, each made out of six centuriae of eighty men. Like in Camp Jupiter, the most prestigious one was the first, then the second, then the third, and so forth. Normally the Centurion of the first centuria commanded the whole Cohort.
The Third Cohort is on the same team with the Fourth and Fifth cohorts during the War Games; who beat the First and Second Cohort in the games. They, along with the Fourth Cohort, stand and watch as the Fifth Cohort begins to lose, but join the fight once the tide is turned in hopes of snatching the glory from the Fifth Cohort.
