Which one is older, sergeant or squad leader?

"Sergeant" is a military rank and "squad leader" is a position, two completely different concepts

On July 13, 2009, the Central Military Commission issued the "Plan for Deepening the Reform of the Noncommissioned Officer System". The entire army and armed police force will fully implement the new non-commissioned officer system before the end of the year. The rank of non-commissioned officers has been adjusted from the original 6 ranks for non-commissioned officers from the first to the sixth class to seven ranks. It is divided into three levels: junior non-commissioned officer, intermediate non-commissioned officer and senior non-commissioned officer. The titles from low to high are as follows

Junior non-commissioned officer: corporal, sergeant

Intermediate non-commissioned officer: staff sergeant, fourth-level sergeant major

Senior non-commissioned officers: Sergeant Major 3rd Class, Sergeant Major 2nd Class, Sergeant Major 1st Class

Also, for example, I joined the army in 2009 and I saw senior privates who joined the army in 2008 or I should call the first-year non-commissioned officer who joined the army in 2007 the squad leader

Anyone who joined the army earlier than me should call him the squad leader

Even if he has retired, I should call him the squad leader if I meet him. It is an unwritten rule to call the squad leader and it is also out of etiquette.

The concept of squad leader

The person in charge of the most basic unit of a military organization

A non-commissioned officer in the militia or army who leads a group of soldiers, with a squad of about 10-12 people .

Squad leader

In grassroots troops and military academies, it also generally refers to all soldiers, students or non-commissioned officers who are older or more senior.

He is the person in charge of the "squad", the most basic organization in the modern army. The squad leader is not an officer, but is usually a non-commissioned officer.

According to the regular establishment of army infantry, a squad is roughly 12 people. The numbers of other branches of the military are slightly smaller and vary from one to another.

According to the queue regulations, the whole class should march in a column, with the squad leader taking the lead and the deputy squad leader behind. Therefore, the last person in the competition is also nicknamed the "vice squad leader".
