The machine gun emplacement was set up. Cao Zhenjiang didn't operate the heavy machine gun but grabbed a light machine gun and went over to Gao Yuan's side. Then, Li Jingang took down a 12.7mm caliber anti-material sniper rifle from the vehicle.
You can't easily abandon the vehicle because the supplies it's carrying are too precious. Everyone has a limited carrying capacity, and without the vehicle, most of the weapons would have to be left behind, which would be a huge loss.

A large-caliber sniper rifle was the most practical and convenient choice.
