SoldierA soldier is a person who is a member of an army. A soldier can be a conscripted or volunteer enlisted person, a non-commissioned officer, a warrant officer, or an officer. The word soldier derives from the Middle English word soudeour, from Old French soudeer or soudeour, meaning mercenary, from soudee, meaning shilling's worth or wage, from sou or soud, shilling. The word is also related to the Medieval Latin soldarius, meaning soldier (literally, "one having pay").
Executive officerAn executive officer is a person who is principally responsible for leading all or part of an organization, although the exact nature of the role varies depending on the organization. In many militaries and police forces, an executive officer, or "XO", is the second-in-command, reporting to the commanding officer. The XO is typically responsible for the management of day-to-day activities, freeing the commander to concentrate on strategy and planning the unit's next move.
Household CavalryThe Household Cavalry (HCav) is made up of the two most senior regiments of the British Army, The Life Guards and The Blues and Royals (Royal Horse Guards and 1st Dragoons). These regiments are divided between the Household Cavalry Regiment stationed at Wing Barracks in Wiltshire and the ceremonial mounted unit, the Household Cavalry Mounted Regiment, garrisoned at Hyde Park Barracks (Knightsbridge Barracks) in London. The Household Cavalry is part of the Household Division and is the King's official bodyguard.
FusilierFusilier is a name given to various kinds of soldiers; its meaning depends on the historical context. While fusilier is derived from the 17th-century French word fusil – meaning a type of flintlock musket – the term has been used in contrasting ways in different countries and at different times, including soldiers guarding artillery, various elite units, ordinary line infantry and other uses. The word fusil, which was the name of the type of musket carried by a fusilier, is itself derived from the Old French and Latin foisil, meaning a piece of flint.
Task forceA task force (TF) is a unit or formation established to work on a single defined task or activity. Originally introduced by the United States Navy, the term has now caught on for general usage and is a standard part of NATO terminology. Many non-military organizations now create "task forces" or task groups for temporary activities that might have once been performed by ad hoc (designated purpose) committees.
