text: Some of the Portuguese uniformed security forces and civil emergency organizations also make use of heraldic standards, guidons and pennants, usually modelled after the military ones.
  United States
  In the United States armed forces, guidons are much more prevalent, with units below battalion size being authorized to use them. In the US Army, these are swallow tailed flags that are 20 in × 27 in, and are in the colour of the branch of the service the unit is from, with the branch's insignia the most prominent device. Also on the guidon is included the unit's identifying letter, and the number(s) of its parent unit. War service and campaign streamers are not attached to these guidons, but unit citation streamers can be.
  Guns
  In regiments of the (British) Royal Artillery, and artillery regiments of other Commonwealth countries, the guns are afforded the status of colours. This is due to the difficulty of artillery regiments being able to carry flags onto the battlefield, and the fact that the guns themselves were the rallying points for the soldiers manning them. As a consequence, whenever artillery regiments parade, the etiquette that would normally be applied to the colours is applied to the guns. During the Battle of Balaclava gunners abandoned their guns, in effect abandoning their colours, causing disgrace.
