Regiment in the context of "Full dress uniform"

Trooping the Colour is a ceremonial event performed every year on Horse Guards Parade in London, United Kingdom, by regiments of Household Division, to celebrate the official birthday of the British sovereign, though the event is not necessarily held on that day. It is also known as the Sovereign's Birthday Parade. Similar events are held in other countries of the Commonwealth. In the UK, it is, with the State Opening of Parliament, the biggest event of the ceremonial calendar, and watched by millions on TV and on the streets of London.

Historically, colours were once used on the battlefield as a rallying point. They display the battle honours of a regiment and are a focal point of Trooping the Colour. The ceremony has marked the sovereign's official birthday since 1748. Each year, one of the five Foot Guards regiments of the Household Division is selected to slowly troop (carry) its colour through the ranks of guards, who stand with arms presented. During the slow march-past, the colours are lowered before the monarch and during the quick march-past the colours fly. The monarch will salute the colours in return.

The Waffen-SS (German: [ˈvafn̩ʔɛsˌʔɛs]; lit. 'Armed SS') was the combat branch of the Nazi Party's paramilitary Schutzstaffel (SS) organisation. Its formations included men from Nazi Germany, along with volunteers and conscripts from both German-occupied Europe and unoccupied lands. With the start of World War II, tactical control was exercised by the Oberkommando der Wehrmacht (OKW, "High Command of the Armed Forces"), with some units being subordinated to the Kommandostab Reichsführer-SS (lit. 'Command Staff Reich Leader-SS') directly under Reichsführer-SS Heinrich Himmler's control. It was disbanded in May 1945.

The Waffen-SS grew from three regiments to over 38 divisions during World War II. Combining combat and police functions, it served alongside the German Army (Heer), Ordnungspolizei (Order Police), and other security units. Originally, it was under the control of the SS Führungshauptamt (SS operational command office) beneath Himmler.

The 7th Cavalry Regiment is a United States Army cavalry regiment formed in 1866. Its official nickname is "Garryowen", after the Irish air "Garryowen" that was adopted as its march tune. The regiment participated in some of the largest battles of the American Indian Wars, including its famous defeat at the Battle of the Little Bighorn, where its commander Lieutenant Colonel George Armstrong Custer was killed. The regiment also committed the Wounded Knee Massacre, where more than 250 men, women and children of the Lakota were killed.

The 7th Cavalry became part of the 1st Cavalry Division in the 1920s, it went on to fight in the Pacific Theater of World War II and took part in the Admiralty Islands, Leyte and Luzon campaigns. It later participated several key battles of the Korean War. During the Korean War the unit committed the No Gun Ri massacre, in which between 250 and 300 South Korean refugees were killed, mostly women and children. The unit later participated in the Vietnam War. It distinguished itself in the Gulf War; the Iraq War (US phase, 2003–2011); and in the War in Afghanistan (2001-2021). Its squadrons and battalions served as Combined Arms Battalions or as reconnaissance squadrons for Brigade Combat Teams in Iraq and Afghanistan.

The French Royal Army (French: Armée Royale Française) was the principal land force of the Kingdom of France. It served the Bourbon dynasty from the reign of Louis XIV in the mid-17th century to that of Charles X in the 19th, with an interlude from 1792 to 1814 and another during the Hundred Days in 1815. It was permanently dissolved following the July Revolution in 1830. The French Royal Army became a model for the new regimental system that was to be imitated throughout Europe from the mid-17th century onward. It was regarded as Europe's greatest military force for much of its existence.

Colonel (/ˈkɜːrnəl/ KUR-nəl; abbreviated as Col., Col, or COL) is a senior military officer rank used in many countries. It is also used in some police forces and paramilitary organizations.

In the 17th, 18th, and 19th centuries, a colonel was typically in charge of a regiment in an army. Modern usage varies greatly, and in some cases, the term is used as an honorific title that may have no direct military relationship. In some smaller military forces, such as those of Monaco or the Vatican, colonel is the highest rank.

Trooper (abbr. Tpr) from the French "troupier" is the equivalent rank to private in a regiment with a cavalry tradition in the British Army and many other Commonwealth armies, including those of Australia, Canada, South Africa and New Zealand; it is also used by the Irish Army.

In the British Army the Royal Tank Regiment, although not a former cavalry unit also uses the term Trooper as do the Special Air Service and Honourable Artillery Company. Airtrooper (Atpr) is used in the Army Air Corps.

A division is a large military unit or formation, usually consisting of between 10,000 and 50,000 soldiers. In most armies, a division is composed of several regiments or brigades; in turn, several divisions typically make up a corps.

Historically, the division has been the default combined arms unit capable of independent operations. Smaller combined arms units, such as the American regimental combat team (RCT) during World War II, were used when conditions favored them. In recent times, modern Western militaries have begun adopting the smaller brigade combat team (similar to the RCT) as the default combined arms unit, with the division to which they belong being less important.

The Royal Regiment of Artillery, commonly referred to as the Royal Artillery (RA) and colloquially known as "The Gunners", is one of two regiments that make up the artillery arm of the British Army.
