Commissioning Ceremony, USMC Officer Candidate School, Quantico, Virginia

The Officer's Oath of Office has its roots in the First Congress of the United States. The oath was revised numerous times until the Forty-Eighth Congress passed the current oath into law by the Act of May 13, 1884. The oath, which may be administered by any officer, reads as follows:

"I do solemnly swear or affirm that I will support and defend the Constitution of the United States against all enemies foreign and domestic; that I will bear true faith and allegiance to the same; that I take this obligation freely without any mental reservation or purpose of evasion; and that I will well and faithfully discharge the duties of the office on which I am about to enter, so help me God."
