What is the grid on the left chest of the military uniform? Specifically?

I found it for your reference. Our army's rank calendar has only two functions: 1. As a supplement to the grade, it indicates the grade. In addition to ranks, officers in our army also have ranks, such as "full rank" and "deputy battalion level". 2, said the service life.

Indicates the job level: 1, and the seniority cards are arranged in rows, with 3 cards in each row. A row of 7 * * * CMC members and CMC vice chairmen, company level 6, company level 5, company level 4, company level 3, battalion level 2, company level 1. In the middle of the top row of each officer, there is a "rank brief". The vice-chairmen and members of the CMC wear the 1 star emblem consisting of five-star and round olive branches. The following ranks are decorated with stars, 2 in the chief position, 1 in the deputy chief position, in which the rank above is Venus and the rank below is Silver Star. There are also differences in the background color of the brochure: the members and vice-chairmen of the Military Commission are lemon yellow, the directors and deputies are orange, the directors and deputies are khaki, the directors and deputies are red, the directors and deputies are purple, the directors and deputies are blue and the directors and deputies are grass green. Look at the sketch in the middle of the top row and you will know the rank of the officer. Because each rank of our army corresponds to several ranks, for example, a major may be a battalion level or a deputy regiment level. This is a supplement to the rank.

Length of military service: The functions of all other chapters are used to represent length of military service. Add up all the marks on the sketch, and it is this officer's length of military service. There are six kinds of short chapters in length of military service, * * *, 10, 5, 4, 3, 2, 1, together.

If an officer is dissatisfied with the platoon, there is also a "supplementary chapter" with a silver-gray background to fill the dissatisfied platoon and keep it beautiful.

When wearing, put the stamps into the stainless steel slideway like a slider. The three stamps are 1 row, and each row of slideways can be connected with each other.

For example, a commander (general) of a major military region who has served for 40 years has 18 in the sixth row. He should wear two orange gold star badges in the eye-catching first row, and the remaining 17 are just doing math problems. Fill in the blanks with those six numbers, and fill in the blanks with supplementary badges. In this way, every year, officers will change a short chapter.

Look at this picture: female air force major in the middle: 6 in 2 rows, vice battalion, and there is a star in the middle with the blue rank abbreviation: vice battalion. Top row 1 track, bottom row from left 1 track, 1 track, 3 tracks, 4 tracks, the last five ribbons, five years, that is, length of military service 15. The female air force captain in the back: 1, three rows, two stars in the middle, or even one level. 2 lanes on the left and 5 lanes on the right, length of military service for 7 years.

The picture below is a close-up of length of military service. From top left to bottom right, it is 1 year four chapters, 2-year four chapters, 3-year four chapters, 4-year three chapters, 5-year two chapters, 1 year1chapter and two supplementary chapters. Supplementary chapter is used for decoration in case of dissatisfaction.
