Context paragraphs:
Australian and New Zealand Army Corps: The Australian and New Zealand Army Corps (ANZAC) was a First World War army corps of the Mediterranean Expeditionary Force.  It was formed in Egypt in December 1914, and operated during the Battle of Gallipoli.  General William Birdwood commanded the corps, which comprised troops from the First Australian Imperial Force and 1st New Zealand Expeditionary Force.  The corps disbanded in 1916, following the Allied evacuation of the Gallipoli peninsula and the formation of I ANZAC Corps and II ANZAC Corps.  The Corps was reestablished, briefly, in the Second World War during the Battle of Greece in 1941.

Marine Corps Expeditionary Medal: The Marine Corps Expeditionary Medal is a military award of the United States Marine Corps.  It was established on 8 May 1919 as the "Marine Corps Expeditionary Ribbon".  A full-sized medal was authorized on 1 March 1921 by Presidential Order of Warren G. Harding.  The Marine Corps Expeditionary Medal is therefore one of the oldest medals of the United States military which is still issued to active duty personnel.

1943–1944 Italian campaign medal: The 1943–1944 Italian campaign medal (French: "Médaille commémorative de la campagne d'Italie 1943-1944" ) was a French commemorative campaign medal awarded to soldiers and sailors who served on Italian soil or Italian waters as part of the "French Expeditionary Corps of Italy" (French: ""Corps Expéditionaire Français (CEF)"" ) under the command of general Alphonse Juin.

Corps expéditionnaire d'Orient: The Corps Expeditionnaire d'Orient (Oriental Expeditionary Force) (CEO) was a French Expeditionary Force raised for service during the Gallipoli Campaign in World War I.  The corps initially consisted of a single infantry division that was raised in North Africa from metropolitan French and French colonial African soldiers, but later grew to two divisions.  It took part in fighting around Kum Kale, on the Asiatic side of the Dardanelles, at the start of the campaign before being moved to Cape Helles where it fought alongside British formations for the remainder of the campaign.  In October 1915, the corps was reduced to one division again and was finally evacuated from the Gallipoli Peninsula in January 1916 when it ceased to exist.

Canadian Expeditionary Force: The Canadian Expeditionary Force (CEF) was the designation of the field force created by Canada for service overseas in the First World War.  The force fielded several combat formations on the Western Front in France and Belgium, the largest of which was the Canadian Corps, consisting of four divisions.  The Canadian Cavalry Brigade and the Canadian Independent Force, which were independent of the Canadian Corps, also fought on the Western Front.  The CEF also had a large reserve and training organization in England, and a recruiting organization in Canada.  In the later stages of the European war, particularly after their success at Vimy Ridge and Passchendaele, the Canadian Corps was regarded by friend and foe alike as the most effective Allied military formation on the Western Front.  The Germans went so far as to call them "storm troopers" for their great combat efficiency.  In August 1918, the CEF's Canadian Siberian Expeditionary Force travelled to revolution-torn Russia.  It reinforced an anti-Bolshevik garrison in Vladivostok during the winter of 1918–19.  At this time, another force of Canadian soldiers were placed in Archangel, where they fought against Bolsheviks.

Free France: Free France and its Free French Forces (French: "France Libre" and "Forces françaises libres") were the government-in-exile led by Charles de Gaulle during the Second World War and its military forces, that continued to fight against the Axis powers as one of the Allies after the fall of France.  Set up in London in June 1940, it was organised and supported the Resistance in occupied France.

Portuguese Expeditionary Corps: The Portuguese Expeditionary Corps (CEP, Portuguese: "Corpo Expedicionário Português") was the main military force from Portugal that fought in the Western Front, during World War I.  Portuguese neutrality ended in 1916 after the seizure of German merchant ships resulted in Germany declaring war.  The expeditionary force was raised soon after and included around 55,000 soldiers.

French Expeditionary Corps (1943–44): The French Expeditionary Corps (French: "Corps Expéditionnaire Français, CEF" ), also known as the "French Expeditionary Corps in Italy" (French: "Corps Expéditionaire Français en Italie, CEFI" ), was an expeditionary force composed of Free French soldiers that fought in the Italian Campaign during World War II under the command of General Alphonse Juin.

French Far East Expeditionary Corps: The French Far East Expeditionary Corps (French: "Corps Expéditionnaire Français en Extrême-Orient, CEFEO" ) was a colonial expeditionary force of the French Union Army that was initially formed in French Indochina during 1945 during the Pacific War.  The CEFEO later fought and lost in the First Indochina War against the Viet Minh rebels.

Keelung Campaign: The Keelung Campaign (August 1884–April 1885) was a controversial military campaign undertaken by the French in northern Formosa (Taiwan) during the Sino-French War.  After making a botched attack on Keelung in August 1884, the French landed an expeditionary corps of 2,000 men and captured the port in October 1884.  Unable to advance beyond their bridgehead, they were invested inside Keelung by superior Chinese forces under the command of the imperial commissioner Liu Mingchuan.  In November and December 1884 cholera and typhoid drained the strength of the French expeditionary corps, while reinforcements for the Chinese army flowed into Formosa via the Pescadores Islands, raising its strength to 35,000 men by the end of the war.  Reinforced in January 1885 to a strength of 4,500 men, the French won two impressive tactical victories against the besieging Chinese in late January and early March 1885, but were not strong enough to exploit these victories.  The Keelung campaign ended in April 1885 in a strategic and tactical stalemate.  The campaign was criticised at the time by Admiral Amédée Courbet, the commander of the French Far East Squadron, as strategically irrelevant and a wasteful diversion of the French navy.
