due to the prior experience possessed by the newly appointed warrant officers. They are assigned to India Company at Camp Barrett. An enlisted Marine can apply for the warrant officer program after serving at least eight years of enlisted service, and reaching the grade of E-5 (Sergeant) for the administrative warrant officer program. For the Marine Warrant Officer (Gunner) program, a Marine must have at least sixteen years of enlisted service in an infantry MOS. This requirement is waived for those holding the rank of Gunnery Sergeant for a minimum of one year prior to applying for the weapons warrant officer program. Sergeants or Staff NCOs who are selected are given additional leadership and management training during the Warrant Officer Basic Course. Infantry Officer Course (IOC) Graduates of the BOC who are selected for an infantry MOS remain at TBS for the fifteen-week Infantry Officer Course. This course was just extended from twelve weeks to better develop the infantry officers. During this program lieutenants receive intensive classroom instruction, practical experience, and field training in crew-served weapons, patrolling, and reconnaissance to ensure that they are MOS qualified for all of the infantry platoon commander billets, in addition to the rifle platoon, within a Marine infantry battalion. The other infantry billets are: rifle company weapons platoon (i.e., crew-served weapons) commander, as well as commander of one of the three heavy-weapons platoons (viz., 81mm mortar, antiarmor, and heavy machine gun) of the infantry battalion weapons company. Infantry officers may seek to compete for a tour as a reconnaissance platoon commander after serving an initial tour with an infantry unit. Officers selected to serve in a Light Armored Reconnaissance (LAR) battalion complete an additional six-week LAR leaders course conducted at the USMC School of Infantry. "Mike" Company Marines who first arrive from OCS or the USNA, or who are unable to complete the BOC, WOBC, or IOC for either failing one of the three graded categories or are significantly injured are sent to M Company, or "Mike Company." Marines in Mike Company provide support operations for companies that are actively training, as well as attend classes and physical events, until they can be given a new USMC MOS if they come from IOC, or resume training if they have yet to complete WOBC or BOC. Mike Company also has Marines who graduated from BOC but are awaiting MOS school pickup. See also United States
