full_context: Document 1: Samuel Nicholas: Samuel Nicholas (1744 – 27 August 1790) was the first officer commissioned in the United States Continental Marines (predecessor to the United States Marine Corps) and by tradition is considered to be the first Commandant of the Marine Corps.
Document 2: United States Armed Forces: The history of the U.S. Armed Forces dates to 14 June 1775, with the creation of the Continental Army, even before the Declaration of Independence marked the establishment of the United States. Continental Navy, established on 13 October 1775, and Continental Marines, established on 10 November 1775, were created in close succession afterwards by the Second Continental Congress in order to defend the new nation against the British Empire in the American Revolutionary War.
Document 3: Surgeon General of the United States: In 1798, Congress established the Marine Hospital Fund, a network of hospitals that cared for sick and disabled seamen. The Marine Hospital Fund was reorganized along military lines in 1870 and became the Marine Hospital Service -- predecessor to today's United States Public Health Service. The service became a separate bureau of the Treasury Department with its own staff, administration, headquarters in Washington, D.C, and the position of Supervising Surgeon (later Surgeon General).
Document 4: Marine Scout Sniper Rifle: The Marine Scout Sniper Rifle or MSSR is a semi-automatic sniper rifle developed from the Colt M16A1 rifle by the Philippine Marine Corps Scout Snipers due to the lack of a dedicated sniper rifle which is used in the Armed Forces of the Philippines.
Document 5: Remington Model 700: The Remington Model 700 is a series of bolt-action centerfire rifles manufactured by Remington Arms since 1962. It is a development of the Remington 721 and 722 series of rifles, which were introduced in 1948. The M24 and M40 military sniper rifles used by the US Army and USMC are both based on the Model 700 design.
Document 6: Jacob Zeilin: Jacob Zeilin (July 16, 1806 – November 18, 1880) was the United States Marine Corps' first non-brevet flag officer. He served as the seventh commandant of the United States Marine Corps, from 1864 to 1876.
Document 7: SA80: The SA80 is a British family of 5.56 × 45mm NATO small arms, all of which are selective fire, gas - operated assault rifle s. The L85 rifle variant of the SA80 family has been the standard issue service rifle of the British Armed Forces since 1987, replacing the L1A1 variant of the FN FAL. The first prototypes were created in 1976, with production ending in 1994. The A1 variant was significantly upgraded in the early 2000s by Heckler & Koch as the SA80A2 and remains in service as of 2017. In mid-2016 a prototype A3 variant was showcased which further improved on the weapon and is reportedly being considered to extend the out of service date beyond 2025.
Document 8: Continental Army: On June 15, 1775, the Congress elected by unanimous vote George Washington as Commander - in - Chief, who accepted and served throughout the war without any compensation except for reimbursement of expenses.
Document 9: United States Marine Corps: After the war, the Marine Corps fell into a malaise that ended with the appointment of Archibald Henderson as its fifth Commandant in 1820. Under his tenure, the Corps took on expeditionary duties in the Caribbean, the Gulf of Mexico, Key West, West Africa, the Falkland Islands, and Sumatra. Commandant Henderson is credited with thwarting President Jackson's attempts to combine and integrate the Marine Corps with the Army. Instead, Congress passed the Act for the Better Organization of the Marine Corps in 1834, stipulating that the Corps was part of the Department of the Navy as a sister service to the Navy. This would be the first of many times that the independent existence of the Corps was challenged.
Document 10: Winchester Model 70: One of the reasons the U.S. Marine Corps replaced their Winchester Model 70s was that the post-1964 variants of the Model 70 did not meet U.S. Marines' standards. Despite the introduction of the Remington Model 700 rifle, the pre-1964 Winchester Model 70 was still used by the US Marine Corps' scout/sniper teams during the Vietnam War alongside the Remington Model 700 rifle. The original wood stocks were found to be warping in both rifles after a few years of service and both rifles were given fiberglass stocks to remedy the problem. Existing Model 70s still in service have had their stocks replaced with a McMillan fiberglass stock, such as that found on the Custom Extreme Weather variant.
Document 11: Zastava M07: The Zastava M07 is a modern military sniper rifle developed and manufactured by Zastava Arms, Serbia. The M07 rifle is based on the Mauser 98 bolt action, and the barrel is made of chrome-vanadium steel. The rifle is loaded from a detachable magazine with a capacity of 5 rounds.
Document 12: Accuracy International Arctic Warfare: The Accuracy International Arctic Warfare model has since spawned an entire family of sniper rifles using the Arctic Warfare name, and has been adopted by a number of other countries, including Australia, Belgium, Germany, Indonesia, Ireland, Latvia, Malaysia, Norway, the Netherlands, New Zealand, Russia, Singapore, Spain, Sweden and the United Kingdom. Other AI rifles descended from the L96A1 include the AI AE, and the AI AS50 (see "variants" below).
Document 13: M40 rifle: The M40 rifle is a bolt-action sniper rifle used by the United States Marine Corps. It has had four variants—the M40, M40A1, M40A3, and M40A5. The M40 was introduced in 1966. The changeover to the A1 model was completed in the 1970s, the A3 in the 2000s, and the A5 in 2009.
Document 14: Jethro Sumner: Sumner was named the commanding officer of the 3rd North Carolina Regiment of the North Carolina Line, a formation of the Continental Army, in 1776, and served in both the Southern theater and Philadelphia campaign. He was one of five brigadier generals from North Carolina in the Continental Army, in which capacity he served between 1779 and 1783. He served with distinction in the battles of Stono Ferry and Eutaw Springs, but recurring bouts of poor health often forced him to play an administrative role, or to convalesce in North Carolina. Following a drastic reduction in the number of North Carolinians serving with the Continental Army, Sumner became a general in the state's militia but resigned in protest after the North Carolina Board of War awarded overall command of the militia to William Smallwood, a Continental Army general from Maryland. After the end of the war in 1783, Sumner helped to establish the North Carolina Chapter of the Society of the Cincinnati, and became its first president. He died in 1785 with extensive landholdings and 35 slaves.
Document 15: United States Marine Corps: The history of the Marine Corps began when two battalions of Continental Marines were formed on 10 November 1775 in Philadelphia as a service branch of infantry troops capable of fighting on both at sea and on shore. By the mid-20th century, the U.S. Marine Corps had become a major theorist of amphibious warfare, which were utilized in the Pacific theater of World War II. As of 2016, the USMC has around 182,000 active duty members and some 38,500 reserve Marines. It is the smallest U.S. military service within the DoD.
