The 63rd has taken part in the Seven Years War, the American Rebellion, the Napoleonic Wars, and the Crimean War. Some of the battles in which the 63rd fought include Bunker Hill (1775), Brandywine (1776), Monmouth (1778), Guadaloupe (1809), Martinique (1810), Inkerman (1854) and the Siege of Sevastopol (1854-55).
More recently, the Regiment took part in the Second Afghan War in 1878.
Some officers and men of the 63rd wear either a Glengarry cap or local ulurr straw hat in place of the typical sun helmet. Officers sometimes exchange the standard scarlet tunic/jacket for a dark blue patrol jacket. Officers may also wear riding pants and boots, and most forego the leggings issued to the NCOs and Other Ranks.
