In the British Army, an NCO is a soldier with rank who leads other soldiers, but who did not take the path that makes a commissioned officer (the kind who start as lieutenants). The letters stand for non-commissioned officer.

In the British Army在英國陸軍裡， an NCO NCO（士官） is是 a soldier with rank who leads other soldiers一位帶有官階、率領其他士兵的軍人， but but 是 who did not take the path that makes a commissioned officer但沒有走上成為委任軍官的那條路 (the kind who start as lieutenants)（也就是從少尉開始做起的那種軍官）。The letters這幾個字母 stand for代表的是 non-commissioned officer non-commissioned officer（非委任軍官）。

In practice this usually means ranks such as corporal and sergeant: people who often have years in the job and who run the day-to-day life of a unit, while a young commissioned officer may still be learning.

In practice實務上 this這 usually means通常指的是 ranks such as corporal and sergeant像下士、中士這樣的官階： people人員 who often have years in the job常常已經做了好幾年 and而且 who run the day-to-day life of a unit負責管理一個單位的日常事務， while a young commissioned officer may still be learning而年輕的委任軍官可能都還在學習階段。

Though actually, soldiers themselves often keep the word “officer” for the commissioned kind, so the tidy dictionary line “officer of low rank” is a little neater than army talk.

Though actually不過其實， soldiers themselves士兵自己 often keep the word “officer” for the commissioned kind常常把「officer」這個詞留給委任軍官在用， so所以 the tidy dictionary line “officer of low rank”字典上「低階軍官」這種乾淨的說法 is a little neater than army talk比起軍隊裡實際的講法要整齊一點。

It is a military word. Civilians mostly meet it in news, history, or films. Other countries have NCOs too, but this sense is the British-army one.
