Based on a reference from the hagiography of St. Joannicius the Great (762–846), who was himself recruited into the regiment and served there until deserting it following the Battle of Marcellae, in 773 the regiment itself was divided into at least eighteen "banda", probably each commanded by a "skribōn" (σκρίβων), showing the retention of the role of the earlier "scribones" as the main subaltern officers of the regiment. Each "bandon" was further divided into sub-units headed by a "drakonarios" (δρακονάριος, deriving from the late Roman "draconarius"). The post was originally that of a standard-bearer, but after Constantine V's reforms, the "drakonarioi" probably functioned as junior officers. The junior officers also included the "skeuophoroi" (σκευοφόροι, "standard carriers"), "signophoroi" (σιγνοφόροι, i.e. signifers) and "sinatores" (σινάτορες, from the late Roman rank of "senator", now much reduced in prominence). There were also the usual messengers (μανδάτορες, "mandatores") under a "prōtomandatōr", some of whom were also termed "legatarioi" (λεγατάριοι), possibly entrusted with police duties.
