"F" Company, but have been divided into "G", "H", and "I" Companies today. "I" Company had been named "I" Troop for all college cadets wishing to participate in equitation. It was once known as "I" Battery for college cadets participating in artillery, but it has now been moved to the collegiate infantry battalion as I Company. Presently, Cadets of the Sixth, Fifth, and Fourth Classes (Grades 7, 8, and 9) are assigned to the "C" Company; formerly, Cadets of the Middle School (Grades 7 and 8) were assigned to the "E" Battery. During the years of highest enrollment, in the 1960s and 1970s, Cadets of the Middle School were assigned to the "H" Company. During the 2009–2010 academic year, given rapid expansion in enrollment, College Cadets have since transferred to the "H" Company. F Company, which formerly had the college cadets, was reformed in 2014 as part of the academy. Initially, the Corps of Cadets was organized, in the same manner as West Point, as a squadron/battalion of infantry companies with a cavalry troop, under a cadet major, who wore five gold chevrons with an oak leaf. Cadet captains wore four chevrons; cadet lieutenants wore three chevrons, sergeants, and corporals three and two, respectively. Rank insignia then mirrored the USMA. Artillery made their debut in the corps (as E Battery) in 1939, formerly in the machine gun role. Later, the school reorganized the Corps into three battalions: two infantry battalions and a mounted battalion (squadron) of one to two troops and one to two artillery batteries, thus becoming a full regiment or brigade in the process. A cadet lieutenant colonel then headed the corps. The corps and the rank system have since evolved. Cadet officers wear gold rank stars or "pips." Pips are similar in design to the "Order of the Bath" rank stars worn by the British Army and the Royal Marines, except the three crowns have been replaced with an image of George Washington kneeling in the snow, from the painting "The Prayer at Valley Forge" by Henry Brueckner, and the motto "Tria Juncta In Uno" replaced with "Valley Forge Military Academy," as represented in the institutional coat of arms. (Before the design of the school "pips", cadet officers wore the British "pips" design with the crowns.) The school also adopted the rank system from the British Army, Royal Marines, the United States Army, and the United States
