The repeated assaults from the enemy made Luo Zheng extremely angry. Looking at the dozen or so flashlights illuminating the path up the mountain from behind the trees at the mountain foot, Luo Zheng knew this was the enemy lighting the way for their advancing forces. Although wearing Night Vision Devices could make the path clear, encountering High-explosive Hand Grenades and RPG attacks might not kill but will definitely injure the eyes and render someone combat ineffective. The enemy wised up, removed their Night Vision Devices, and switched to flashlights for illumination.
