Before a battle, or on parade, the emperor would address his troops in an event known as an adlocutio cohortium (address to the cohorts). This was an important opportunity for the emperor to be present among his troops to inspire morale. This sestertius was issued on the occasion of a donative for the Praetorian Guard and was the first to employ the adlocutio as a reverse type.
