It is likely Rock's official position in Easy Company was of senior platoon sergeant though dialogue and scripts are usually vague on his actual responsibilities and duties. He usually leads patrols and appears to have powers of command over the men of the company. Several officer characters also appeared in the comic, as both platoon and company commanders, all of whom were regarded by Rock as superiors. Ever the model NCO, Sgt. Rock always rendered proper respect to these officers, and was always quick to give advice to not only ensure success, but for that officer to gain confidence and experience as a leader. Easy's commander was usually referred to as "the skipper" by Rock. Rock in turn was referred to by others as the "topkick", or senior non-commissioned officer in the company. Most infantry companies did not have master sergeants; significantly, Rock does not have the diamond of a first sergeant on his rank insignia.
