1. An officer is a person with power or command position in the army, especially a person with orders, that is, an army cadre.

2. Soldiers are the most basic combatants in the army, including non-commissioned officers (professional soldiers) and conscripts (ordinary soldiers) in China.

3. Non-commissioned officers, or "professional soldiers", have higher status than soldiers (ordinary soldiers).

Second, the conceptual differences.

1. officers: generally, they are composed of qualified military schools, national defense graduates, entrusted civilian cadres and professional and technical personnel recruited from local areas under special circumstances. Divided into two categories: command category and technical category. In the army, they are generally called core personnel (command) and non-core personnel (technology).

2. Non-commissioned officers: The former volunteers were transferred to non-commissioned officers upon the application of soldiers who had served for two years. The epaulettes are a pattern of turning+two shots and one star. They are divided into six levels of non-commissioned officers according to the age of soldiers. It's clear upstairs, so I won't talk nonsense. The rank of a petty officer can be known by the thickness and number of crutches.

Third, the subdivision levels are different.

1, the ranks of officers in our army are divided into three grades and ten grades:

General officer level 3: general, lieutenant general and major general;

University official level 4, senior colonel, colonel, lieutenant colonel and major;

Junior officers are divided into three levels: captain, lieutenant and second lieutenant.

2. From low to high, non-commissioned officers are called corporal, sergeant, staff sergeant, fourth-level master sergeant, third-level master sergeant, second-level master sergeant and first-level master sergeant.
