What is the oldest unit in history?

The army is the oldest service in China with a long history of development.

From the Shang Dynasty, the Western Zhou Dynasty to the mid-Spring and Autumn Period, there were soldiers and chariots in the army for hiking and chariot fighting. It is mainly equipped with bronze weapons such as chariots, daggers, spears, halberds and swords, as well as protective equipment such as bronze armor and leather armor, with golden drums and flags as communication tools for commanding operations.

After the mid-Spring and Autumn Period, the status of chariots declined and that of infantry rose. At the end of the Spring and Autumn Period, cavalry began to appear.
