Myanmar.
Su Yu's confrontation zone with Myanmar.
The entire confrontation zone is very long, almost fifty kilometers, which is a headache for both sides. How to defend has been great trouble, hence the tacit agreement over these many years.
The whole confrontation zone has been divided into five sections, each section having a place where soldiers would concentrate.
Both sides constructed a large amount of permanent fortifications and deployed numerous soldiers. Half of Su Yu's forces were placed here, and the rest of the line was merely sporadically placed guard posts and an unknown number of minefields.
Especially between the five permanent positions of both sides, the ground was full of mines. Both sides were somewhat unclear about the exact number because it had been too long, and only a safe route known to oneself was left.
This was exactly why.
