What is the use of the slogan of marching troops?

Mainly the commander adjusts the pace of the queue. Usually, "1" is issued when the left foot lands, and "2" is issued when the right foot lands. "12 1" is mainly used for recruit training. Recruits can't walk well in the queue, and it is easy to go wrong or can't keep up with the rhythm. This password is issued to remind those who are wrong and can't keep up with the rhythm.

In addition, it is also to boost morale.

During the procession, commanders and queue members shouted slogans, passwords and songs, one for morale and the other for the uniformity of the procession.
