 While the "limitanei" were supposed to deal with policing actions and low-intensity incursions, the duty of responding to more serious incidents fell upon the provincial troops.The countering of the very largest scale incursions on a strategic scale was the task of the "comitatenses" and "palatini" or mobile field troops, possibly accompanied by the emperor's "scholae".Both border and field armies consisted of a mix of infantry and cavalry units although the weight of cavalry was, according to some authorities, greater in the mobile field armies.
