A battle honour is an award of a right by a government or sovereign to a military unit to emblazon the name of a battle or operation on its flags ("colours"), uniforms or other accessories where ornamentation is possible. In European military tradition, military units may be acknowledged for their achievements in specific wars or operations of a military campaign. In Great Britain and those countries of the Commonwealth which share a common military legacy with the British, battle honours are awarded to selected military units as official acknowledgement for their achievements in specific wars or operations of a military campaign. These honours usually take the form of a place and a date (e.g. "Cambrai 1917"). Theatre honours, a type of recognition in the British tradition closely allied to battle honours, were introduced to honour units which provided sterling service in a campaign but were not part of specific battles for which separate battle honours were awarded. Theatre honours could be listed and displayed on regimental property but not emblazoned on the colours. Since battle honours are primarily emblazoned on colours, artillery units, which do not have colours in the British military tradition, were awarded honour titles instead. These honour titles were permitted to be used as part of their official nomenclature, for example 13 Field Regiment (Chushul). Similar honours in the same tenor include unit citations. Battle honours, theatre honours, honour titles and their ilk form a part of the wider variety of distinctions which serve to distinguish military units from each other. In the British military tradition Origins For the British Army, the need to adopt a system to recognise military units' battlefield accomplishments was apparent since its formation as a standing army in the later part of the 17th century. Although the granting of battle honours had already been in place at the time, it was not until 1784 that infantry units were authorised to bear battle honours on their colours. Before then, a regiment's colours were practical tools for rallying troops in the battlefield and not quite something for displaying the unit's past distinctions. The first battle honour to be awarded in the British Army was granted to the 15th Hussars for the Battle of Emsdorf in 1760. Thereafter, other regiments received battle honours for some of their previous engagements. The earliest battle honour in the British Army is Tangier 1662–80, granted to the Tangier Horse
