She had to carefully inspect every one of them, then use the information within to coordinate and fine-tune the mobile patrols, ensuring there were no obvious defensive gaps while also preventing the patrols from developing a pattern that the enemy could spot and exploit to infiltrate.
After all, irregular mobile patrols were a special patrol method designed for situations with insufficient manpower, but they were not foolproof.

Their coverage rate was basically ninety-nine percent.
