Information: - A soldier is one who fights as part of an organised, land-based armed force. A soldier can be an enlisted person, a non-commissioned officer, or an officer. - In many militaries, a platoon sergeant is the senior enlisted member of a platoon, who advises and supports the platoon's commanding officer in leading the unit. - Junior officer, company officer or company grade officer refers to the lowest operational commissioned officer category of ranks in a military or paramilitary organization, ranking above non-commissioned officers and below senior officers. - A section is a military sub-subunit in some armies . In many armies , it might be a squad of 2 - 3 fireteams ( i.e. seven to twelve soldiers ) . However , in France and armies based on the French model , it is the sub-division of a company ( equivalent to a platoon ) . - A lieutenant (abbreviated Lt., LT, LTA, Lieut., LEUT and LEUT.) is a junior commissioned officer in many nations' armed forces, fire service or police. - In military terminology, a squad is a sub-subunit led by a non-commissioned officer that is subordinate to an infantry platoon. In countries following the British Army tradition (Australian Army, Canadian Army, and others), this organization is referred to as a section. In most armies, a squad consists of eight to fourteen soldiers, and may be further subdivided into fireteams. - A platoon is a military unit typically composed of two or more squads/sections/patrols. Platoon organization varies depending on the country and the branch, but typically a platoon consists of around 40 to 50 soldiers. A platoon leader or commander is the officer in command of a platoon. This person is usually a junior officera second or first lieutenant or an equivalent rank. The officer is usually assisted by a platoon sergeant. A platoon is typically the smallest military unit led by a commissioned officer. - The Australian Army is Australia's military land force. It is part of the Australian Defence Force (ADF) along with the Royal Australian Navy and the Royal Australian Air Force. While the Chief of the Defence Force (CDF) commands the ADF, the Army is commanded by the Chief of Army (CA). The CA is therefore subordinate to the CDF, but is also directly responsible to the Minister for Defence. Although Australian soldiers have been involved in a number of minor and major conflicts throughout its history, only in World War II has Australian territory come under direct attack. - Sergeant (abbreviated to Sgt and capitalised when used as a named person's title) is a rank in many uniformed organizations, principally military and policing forces. Its origin is the Latin "serviens", "one who serves", through the French term "sergent". - A patrol is commonly a group of personnel, such as law enforcement officers or military personnel, that are assigned to monitor a specific geographic area. - A fireteam is a small military sub-subunit of infantry designed to optimize "bounding overwatch" and "fire and movement" tactical doctrine in combat. Depending on mission requirements, a typical fireteam consists of 4 or fewer members; an assistant automatic rifleman, an automatic rifleman, a rifleman, and a designated team leader; the role of each fireteam leader is to ensure the fireteam operates as a cohesive unit. Two or three fireteams are organized into a squad or section in coordinated operations, which is led by a squad leader. - A platoon leader (NATO) or platoon commander (more common in Commonwealth militaries and the US Marine Corps) is the officer in command of a platoon. This person is usually a junior officer a second or first lieutenant or an equivalent rank. The officer is usually assisted by a platoon sergeant. Some special units, such as specific aviation platoons and special forces, require a captain as platoon leader, due to the nature and increased responsibility of such assignments. Platoons normally consist of three or four sections (Commonwealth) or squads (US). - A non-commissioned officer or noncommissioned officer (NCO, colloquially non-com or noncom) is a military officer who has not earned a commission. Such is also called sub-officer in some countries. Non-commissioned officers, in the English-speaking world, usually obtain their position of authority by promotion through the enlisted ranks. In contrast, commissioned officers hold higher ranks than NCOs, have more legal responsibilities, are paid more, and often have more non-military training such as a university diploma. Commissioned officers usually earn their commissions without having risen through the enlisted ranks. "Mustang" is a slang term in the United States Armed Forces used to refer to a commissioned officer who began his or her career as an enlisted service member. - Infantry is the general branch of an army that engages in military combat on foot. As the troops who engage with the enemy in close-ranged combat, infantry units bear the largest brunt of warfare and typically suffer the greatest number of casualties during a military campaign. Historically, as the oldest branch of the combat arms, the infantry are the tip of the spear of a modern army, and continually undergo training that is typically more physically demanding and psychologically stressful than that of any other branch of the combat arms. Common representations of infantry fighting forces include the U.S. Army Infantry Branch, U.S. Marine Corps Infantry, Royal Canadian Infantry Corps, Infantry of the British Army, and the Royal Australian Corps of Infantry. - The British Army is the principal land warfare force of the United Kingdom. The force was initially administered by the War Office from London, which in 1964 was subsumed into the Ministry of Defence. The professional head of the British Army is the Chief of the General Staff. Given the paragraphs above, decide what entity has the relation 'instance of' with 'military unit'.
