RMC was established in 1876 and is the only federal institution in Canada with degree-granting powers.  The Royal Military College of Canada Degrees Act, 1959 empowers the college to confer degrees in arts, science, and engineering.  Programs are offered at the undergraduate and graduate levels both on campus as well as through the College's distance learning programme via the Division of Continuing Studies.

Reserve Officers' Training Corps: The Reserve Officers' Training Corps (ROTC) are a group of college-based officer training programs for training commissioned officers of the United States Armed Forces.  ROTC officers serve in all branches of the U.S. armed forces (although the U.S. Marine Corps and the U.S. Coast Guard do not have their own respective ROTC programs, graduates of ROTC programs do currently serve as Marine Corps and Coast Guard officers).  In 2010, ROTC graduates constituted 38.5 percent of newly commissioned U.S. Army officers, 1.8 percent of newly commissioned U.S. Marine Corps officers (through NROTC), 16.7 percent of newly commissioned U.S. Navy officers, and 38.1 percent of newly commissioned U.S. Air Force officers, for a combined 30 percent of all active duty officers in the Department of Defense commissioned that year.  Under ROTC, a student may receive a competitive, merit-based scholarship, covering all or part of college tuition, in return for an obligation of active military service after graduation.

The Institute grants degrees in 14 disciplines in engineering, the sciences, and the liberal arts.

War college: A war college is a senior military academy which is normally intended for veteran military officers and whose purpose is to educate and 'train on' senior military tacticians, strategists, and leaders.

Staff College, Camberley: Staff College, Camberley, Surrey, was a staff college for the British Army and the presidency armies of British India (later merged to form the Indian Army).  It had its origins in the Royal Military College, High Wycombe founded in 1799, which in 1802 became the Senior Department of the new Royal Military College.  In 1858 the name of the Senior Department was changed to "Staff College", and in 1870 this was separated from the Royal Military College.  Apart from periods of closure during major wars, the Staff College continued to operate until 1997, when it was merged into the new Joint Services Command and Staff College.  The equivalent in the Royal Navy was the Royal Naval Staff College, Greenwich and the equivalent in the Royal Air Force was the RAF Staff College, Bracknell.

Marc Garlasco: Marc Garlasco (born September 4, 1970) is an American former Pentagon senior intelligence analyst, now senior civilian protection officer for the United Nations Assistance Mission in Afghanistan (UNAMA) and senior military advisor for the Human Rights Council (HRC).  Having served for seven years at the Pentagon, becoming chief of high-value targeting, Garlasco left in 2003 and joined Human Rights Watch (HRW) as a senior military expert, specializing in battle damage assessment, military operations, and interrogations for the Emergencies Division, where he investigated human rights issues in a number of different conflicts zones.  The author of a World War II German anti-aircraft medals reference book, Garlasco was suspended by HRW with pay, “pending an investigation", on September 14, 2009 after it was alleged that he had collected Nazi memorabilia.  Garlasco downplayed the controversy, insisting he collected German and US World War II memorabilia because of family history and his interest in military history.  He resigned from HRW in February 2010.  Calls have been made for his reports during that time to be reviewed on grounds of bias.  He served as senior civilian protection officer for UNAMA in 2011, heading the UN's Protection of Civilians office.  In early 2012, as the U.N. senior military advisor for the HRC's Independent Commission of Inquiry on Libya, he investigated civilian casualties while leading a survey of NATO's activities in Libya.
