The Real Irish Republican Army or Real IRA (RIRA), also called the New IRA (NIRA) after a merger in 2012, is a dissident Irish republican paramilitary group which aims to bring about a united Ireland. It formed in 1997 following a split in the Provisional IRA by dissident members, who rejected the IRA's ceasefire that year. Like the Provisional IRA before it, the Real IRA sees itself as the only rightful successor to the original Irish Republican Army and styles itself as simply "the Irish Republican Army" in English or Óglaigh na hÉireann in Irish. It is an illegal organisation in the Republic of Ireland and designated as a proscribed terrorist organisation in the United Kingdom and the United States.

The Third Battle of Ypres, also known as the Battle of Passchendaele, was a campaign of the First World War, fought by the Allies against the German Empire. The battle took place on the Western Front, from July to November 1917, for control of the ridges south and east of the Belgian city of Ypres in West Flanders, as part of a strategy decided by the Allies at conferences in November 1916 and May 1917. Passchendaele lay on the last ridge east of Ypres, 5 mi (8.0 km) from the German controlled Roulers junction of the Bruges (Brugge) to Kortrijk railway, the main supply route of the German 4th Army. The next stage was an advance to a line from Thourout to Couckelaere.
The attack on Pearl Harbor was a surprise military strike by the Imperial Japanese Navy Air Service upon the United States against the naval base at Pearl Harbor in Honolulu, Hawaii on Sunday morning, December 7, 1941. The attack led to the United States' formal entry into World War II the next day. The Japanese military leadership referred to the attack as the Hawaii Operation and Operation AI, and as Operation Z during its planning.
The Battle of Midway was a decisive naval battle in the Pacific Theater of World War II that took place between 4 and 7 June 1942, only six months after Japan's attack on Pearl Harbor and one month after the Battle of the Coral Sea. The United States Navy under Admirals Chester W. Nimitz, Frank Jack Fletcher, and Raymond A. Spruance defeated an attacking fleet of the Imperial Japanese Navy under Admirals Isoroku Yamamoto, Chūichi Nagumo, and Nobutake Kondō near Midway Atoll, inflicting devastating damage on the Japanese fleet that proved irreparable. Military historian John Keegan called it "the most stunning and decisive blow in the history of naval warfare", while another naval historian, Craig L. Symonds, called it "one of the most consequential naval engagements in world history, ranking alongside Salamis, Trafalgar, and Tsushima, as both tactically decisive and strategically influential."
The Battle of Leyte Gulf is considered to have been the largest naval battle of World War II and, by some criteria, possibly the largest naval battle in history, with over 200,000 naval personnel involved. It was fought in waters near the Philippine islands of Leyte, Samar, and Luzon, from 23–26 October 1944, between combined American and Australian forces and the Imperial Japanese Navy (IJN), as part of the invasion of Leyte, which aimed to isolate Japan from the countries it had occupied in Southeast Asia which were a vital source of industrial and oil supplies.
Forwards are the players on an association football team who play nearest to the opposing team's goal, and are therefore most responsible for scoring goals.
A midfielder is an association football position. Midfielders are generally positioned on the field between their team's defenders and forwards. Some midfielders play a disciplined defensive role, breaking up attacks, and are otherwise known as defensive midfielders. Others blur the boundaries, being more mobile and efficient in passing: they are commonly referred to as deep-lying midfielders, play-makers, box-to-box, or holding midfielders. The number of midfielders on a team and their assigned roles depends on the team's formation; the collective group of these players on the field is sometimes referred to as the midfield.
In the sport of association football, a defender is an outfield player whose primary role is to prevent the opposing team from scoring goals.
In association football, the formation describes how the players in a team generally position themselves on the pitch. Association football is a fluid and fast-moving game, and a player's position in a formation does not define their role as rigidly as for, for instance, a rugby player, nor are there episodes in play where players must expressly line up in formation. Nevertheless, a player's position in a formation generally defines whether a player has a mostly defensive or attacking role, and whether they tend to play towards one side of the pitch or centrally.
In the sport of association football, each of the 11 players on a team is assigned to a particular position on the field of play. A team is made up of one goalkeeper and ten outfield players who fill various defensive, midfield, and attacking positions depending on the formation deployed. These positions describe both the player's main role and their area of operation on the pitch.

They were shot dead by Metropolitan Police officers and were found to be wearing fake explosive vests. Eight people were killed and 48 were injured, including members of the public and four unarmed police officers who attempted to stop the assailants.
