军事单位

较大的军事组织里具有规定的大小和特定战斗或支援角色的团体。古代主要的军事单位是希腊人的方阵和罗马人的军团。现代军事单位起源於16~18世纪,当时职业军队在中世纪末期以後开始在欧洲出现。从那时起,开始使用的基本单位是营、旅和师,并沿用至今。今天最小的军事单位是班,包括7~14名士兵,由一名士官领导。3个或4个班组成一个排,两个及两个以上的排组成一个连,大约有100~250名士兵,由一名上尉或少校带领。两个及两个以上的连组成一个营,几个营组成一个旅,两个及两个以上的旅以及几个特种营组成一个师,大约有7,000~22,000人,由一名少将带领。2至7个师组成一个军团,由中将带领,最大的师有50,000~300,000人,是常规军队的最大组成形式。但在战争期间,一个或几个军团可能被合起来组成一支野战部队(由一名将军带领),而野战部队也可反过来合为集团军。

military unit

Group of a prescribed size with a specific combat role within a larger military organization. The chief units in the ancient world were the Greek phalanx and the Roman legion. Modern units originated in the 16th-18th century, when professional armies reemerged in Europe after the end of the Middle Ages. Since then the basic units—company battalion, brigade, and division—have remained in use. The smallest unit today is the squad, which has 7-14 soldiers and is led by a sergeant. Three or four squads make up a platoon, and two or more platoons make up a company, which has 100-250 soldiers and is commanded by a captain or a major. Two or more companies make up a battalion, and several battalions form a brigade. Two or more brigades, along with various specialized battalions, make up a division, which has 7,000-22,000 troops and is commanded by a major general. Two to seven divisions make up an army corps, commanded by a lieutenant general, which with 50,000-300,000 troops is the largest regular army formation, though in wartime two or more corps may be combined to form a field army (commanded by a general), and field armies in turn may be combined to form an army group.
