Marines-The backbone of the Corps,organized into squads,the lowest level of infantry organization,each named after animals with their own insignia.Despite the name,squads appear to be more like platoons or companies,with lieutenants as the primary officers and sergeants as squad leaders.Although the squads are infantry,they appear to have members from all branches of the military,with several squads having soldiers who operate equipment on the USS Hannibal.The number of personnel in a Squad appears to vary:from the Rhino troop,numbering nine,to the Raven troop,numbering sixty-three.It is most likely that the troops have their own specific profession;The Rhino Squad is a small,elite special operations unit,while the Raven Squad is a larger,more modern military force.There also seem to be three different lieutenant ranks;third lieutenant,second lieutenant and first lieutenant
