The first platoon of the first company is mainly responsible for earthwork construction, while the second and third platoons are responsible for earthwork transportation.
The fourth platoon is an auxiliary construction unit. The so-called auxiliary tasks are those jobs that machines cannot handle, equivalent to general laborers on a construction site.
Since the auxiliary work requires no technical skills, the platoon is made up of eighteen warriors, all selected from among the "roaming soldiers" sent from various townships and streets without any professional skills.
Each person has a roster, and everyone reviews the list to help assign personnel to the fourth platoon.
This young man was a driver in the army and has skills, so he cannot be assigned to the fourth platoon.
That young man was a cook in the army, a talent urgently needed in the camp, and likewise cannot be assigned to the fourth platoon.
