  Title: Irish in the British Armed Forces
  Passage: The Irish in the British Armed Forces refers to the history of Irish people serving in the British Armed Forces (including the British Army, the Royal Navy, the Royal Air Force and other elements).  Ireland was ruled as part of the United Kingdom from 1800-1922 and during this time in particular many Irishmen fought in the British Army.  Different social classes joined the military for various reasons, including the Anglo-Irish officers who thoroughly identified with the British Empire, while others, typically poorer Irish Catholics did so to feed their families or seeking adventure.  Many Irishmen and members of the Irish diaspora in Britain and also Ulster-Scots served in both World War I and World War II as part of the British forces.  However, especially since the advent of Irish independence and The Troubles, the topic of enlistment in the British forces has been controversial for the Irish at home, but does still occur.  Since partition, Irish citizens have continued to have the right to serve in the British Army.  Since 2007, when troops finally withdrew from the streets of Northern Ireland, the number of Irish citizens joining has increased, reaching its highest levels since World War II.
  Title: United States Army
  Passage: The United States Army (USA) is the largest branch of the United States Armed Forces and performs land-based military operations.

As the oldest and most senior branch of the U.S. military in order of precedence, the modern U.S. Army has its roots in the Continental Army, which was formed (14 June 1775) to fight the American Revolutionary War (1775–1783)—before the United States of America was established as a country.  After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army.  The United States Army considers itself descended from the Continental Army, and dates its institutional inception from the origin of that armed force in 1775.

Players interested in the military and willing to support the mission will continue to pay their own expenses while off-duty to compete against the finest professional, independent and summer collegiate programs in the world.
