He made his debut for the first team in their final match in the English First Division, although he was to wait a further two years for his next appearance. In all Milkins was to make over 300 appearances for Portsmouth and was to prove such a popular player that in 1970 he was awarded the inaugural "Player of the Year" trophy. The following year he was awarded a testimonial against local rivals Southampton which resulted in a 0–7 defeat. In the 1974 close season he was sold to Oxford United for whom he played sporadically until his last league appearance in May 1979. He then joined now defunct Southern League club Waterlooville and, after two years as first-choice goalkeeper, became player-manager during the 1981-82 season.

He was capped once for England at under-21 level. He moved on to Birmingham City in 2003, where he was chosen player of the 2006–07 season, at the end of which he signed for Leicester City. An injury prone player, Clemence was well known for his passion, drive, leadership and commitment on the pitch.

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: Canadian Armed Forces: The responsibility for military command remained with the British Crown-in-Council, with a commander-in-chief for North America stationed at Halifax until the final withdrawal of British Army and Royal Navy units from that city in 1906. Thereafter, the Royal Canadian Navy was formed, and, with the advent of military aviation, the Royal Canadian Air Force. These forces were organised under the Department of Militia and Defence, and split into the Permanent and Non-Permanent Active Militias—frequently shortened to simply The Militia. By 1923, the department was merged into the Department of National Defence, but land forces in Canada were not referred to as the Canadian Army until November 1940.
Document 11: Commander-in-Chief, Portsmouth: The post of Commander-in-Chief, Portsmouth was merged with that of Commander-in-Chief, Plymouth in 1969 to form the post of Commander-in-Chief, Naval Home Command. The posts of Second Sea Lord and Commander-in-Chief Naval Home Command were amalgamated in 1994 following the rationalisation of the British Armed Forces following the end of the Cold War. In 2012, however, all distinct Commander-in-Chief appointments were discontinued, with full operational command being vested instead in the First Sea Lord; he now flies his flag from HMS "Victory".
Document 12: Supreme Commander of the Swedish Armed Forces: The Supreme Commander is, apart from the honorary ranks held by the King of Sweden and in the past other members of the Swedish Royal Family, by unwritten convention normally the only professional military officer on active duty to hold the highest rank (a four-star General or Admiral).

Document 14: History of Manchester City F.C.: A long period of decline followed the success of the 1960s and 1970s. Malcolm Allison rejoined the club to become manager for the second time in 1979, but squandered large sums of money on unsuccessful signings, such as Steve Daley. A succession of managers then followed -- seven in the 1980s alone. Under John Bond, City reached the 1981 FA Cup final but lost in a replay to Tottenham Hotspur. The club were twice relegated from the top flight in the 1980s (in 1983 and 1987), but returned to the top flight again in 1989 and finished fifth in 1991 and 1992 under the management of Peter Reid. However, this was only a temporary respite, and following Reid's departure Manchester City's fortunes continued to fade. City were co-founders of the Premier League upon its creation in 1992, but after finishing ninth in its first season they endured three seasons of struggle before being relegated in 1996. After two seasons in Division One, City fell to the lowest point in their history, becoming the second ever European trophy winners to be relegated to their country's third league tier, after 1. FC Magdeburg of Germany.
Document 15: Canadian Armed Forces: The Canadian Joint Operations Command is an operational element established in October 2012 with the merger of Canada Command, the Canadian Expeditionary Force Command and the Canadian Operational Support Command.
