Military organizationMilitary organization or military organisation is the structuring of the armed forces of a state so as to offer such military capability as a national defense policy may require. In some countries paramilitary forces are included in a nation's armed forces, though not considered military. Armed forces that are not a part of military or paramilitary organizations, such as insurgent forces, often mimic military organizations, or use these structures, while formal military organization tends to use hierarchical forms.
RegimentA regiment is a military unit. Its role and size varies markedly, depending on the country, service and/or a specialisation. In Medieval Europe, the term "regiment" denoted any large body of front-line soldiers, recruited or conscripted in one geographical area, by a leader who was often also the feudal lord in capite of the soldiers. Lesser barons of knightly rank could be expected to muster or hire a company or battalion from their manorial estate.
Division (military)A division is a large military unit or formation, usually consisting of between 6,000 and 25,000 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.
Company (military unit)A company is a military unit, typically consisting of 100–250 soldiers and usually commanded by a major or a captain. Most companies are formed of three to seven platoons, although the exact number may vary by country, unit type, and structure. Usually several companies are grouped as a battalion or regiment, the latter of which is sometimes formed by several battalions. Occasionally, independent or separate companies are organized for special purposes, such as the 1st Air Naval Gunfire Liaison Company or the 3rd Force Reconnaissance Company.
