The science of artillery grew rapidly under the pressure of the Industrial Revolution and by the end of the 19th century, the need for indirect fire brought major changes. Guns became ever more powerful, firing more efficient munitions to longer ranges with increased accuracy and greater speed. The Great War of 1914-18 was to prove an artillery war, and the number of gunners increased dramatically, serving 6,655 guns by the end of the war, with anti-aircraft (AA) guns joining in against the new threat from the air.
The inter-war years provided active service on the fringes of the Empire, but the 1930s saw the Regiment once again arming for war. Full mechanisation now replaced the horses which had served the Regiment for so long. In the war which ensued, the Regiment again provided firepower in every theatre, on land, at sea in the Maritime Artillery, and in the air with Air Observation Posts. Gunners manned huge numbers of AA guns both in the field and in the home base. Many of the AA Regiments were formed from Territorial Army units. Most of the Light AA gunners began the war as infantrymen.
Despite the reduction of the Army in the post-war years, the Regiment has been armed with some of the most potent, long-ranged weapons it has ever manned. Today it uses the wide span of technology of all the Arms, with virtually no branch of military science unexplored.
But the Regiment's history is the foundation stone on which it rests. For over 280 years of unbroken service since 1716, and reaching back a further 400 years to the first bombard, artillerymen have provided the Army with the firepower it has needed in defence and attack. In 1833, King William IV recognised that to continue granting Battle Honours to the Regiment would result in an excessive list, and granted instead a single Battle Honour, the motto Ubique (Everywhere), with an accompanying motto Quo Fas Et Gloria Ducunt (Whither Right and Glory Lead)
