Final answer:
The correct charter for the formation of a Ranger Battalion is not given among the choices, as the Mayflower Compact did not involve military organization, and the other documents refer to other historical or ethical guidelines.
Step-by-step explanation:
The Charter that directed the formation of a Ranger Battalion is not listed among the options provided by the student. The Mayflower Compact was signed in 1620 by the Pilgrims and served as a social contract to establish a provisional government based on the majority rule of the settlers, not the formation of a military unit. The Magna Carta was a document signed in 1215 that curbed the power of the English monarch and cemented principles of law and justice in England.
The Ranger Creed is a statement of values and ethics adhered to by the U.S. Army Rangers. The Darby Ranger Training Charter, while not commonly referred to in historical documents, seems to be the closest to answering the question, likely referring to the standards and protocols for training Army Rangers during World War II, initiated by Lieutenant Colonel William O. Darby.
