The British Expeditionary Force (BEF) was the six divisions the British Army sent to the Western Front during the First World War. Planning for a British Expeditionary Force began with the 1906–1912 Haldane Reforms of the British Army carried out by the Secretary of State for War Richard Haldane following the Second Boer War (1899–1902).
The American Expeditionary Forces (AEF) was a formation of the United States Armed Forces on the Western Front during World War I, composed mostly of units from the U.S. Army. The AEF was established on July 5, 1917, in France under the command of then-Major General John J. Pershing. It fought alongside French Army, British Army, Canadian Army, British Indian Army, New Zealand Army and Australian Army units against the Imperial German Army. A small number of AEF troops also fought alongside Italian Army units in 1918 against the Austro-Hungarian Army. The AEF helped the French Army on the Western Front during the Aisne Offensive in the summer of 1918, and fought its major actions in the Battle of Saint-Mihiel and the Meuse-Argonne Offensive in the latter part of 1918.

They were soon renamed the "Rifle Corps". In January 1803, they became an established regular regiment and were titled the 95th Regiment of Foot (Rifles). In 1816, at the end of the Napoleonic Wars, they were again renamed, this time as the "Rifle Brigade".

The Cameronians (Scottish Rifles) was a rifle regiment of the British Army, the only regiment of rifles amongst the Scottish regiments of infantry. It was formed in 1881 under the Childers Reforms by the amalgamation of the 26th Cameronian Regiment and the 90th Perthshire Light Infantry. In 1968, when reductions were required, the regiment chose to be disbanded rather than amalgamated with another regiment, one of only two infantry regiments in the British Army to do so, with the other being the York and Lancaster Regiment. It can trace its roots to that of the Cameronians, later the 26th of Foot, who were raised in 1689. The 1881 amalgamation coincided with the Cameronian's selection to become the new Scottish Rifles.
The 2nd Infantry Brigade was a regional brigade of the British Army, active since before the First World War.

The Russian Expeditionary Force [REF] was a World War I military force sent to France and Greece by the Russian Empire. In 1915, the French requested that Russian troops be sent to fight alongside their own army on the Western Front. Initially they asked for 300,000 men, an unrealistically high figure, probably based on assumptions about Russia's 'unlimited' reserves. General Mikhail Alekseev, the Imperial Chief of Staff, was opposed to sending any Russian troops, although Nicholas II finally agreed to send a unit of brigade strength. The first Russian brigade finally landed at Marseille in April 1916.

In September 2007, the regiment amalgamated with the Cheshire Regiment and the Staffordshire Regiment to form the Mercian Regiment.

The North Staffordshire Regiment (Prince of Wales's) was a line infantry regiment of the British Army, which was in existence between 1881 and 1959. The 64th (2nd Staffordshire) Regiment of Foot was created on 21 April 1758 from the 2nd Battalion of the 11th Regiment of Foot. In 1881, under the Childers Reforms, the 64th Regiment of Foot was merged with the 98th (Prince of Wales's) Regiment of Foot (originally raised in 1824) to form the Prince of Wales's (North Staffordshire Regiment). In 1921 the regimental title was altered to the North Staffordshire Regiment (Prince of Wales's).
