Prior to 1915 all the Guards Battalions were spread out among different divisions. They were united at the urging of Lord Kitchner in 1915 when the King created the Guards Division.
The King proclaimed that the men who use grenades shall be called "Bombers" and the title "Grenadier" was reserved for the Grenadier Guards.
