The green dots represented soldiers, while the red dots represented criminals.
This wasn't role-playing. The enemies who were assigned here for special training were indeed criminals in prison.
These criminals were all special people with high intelligence and were good at firearms. It was not without benefits to be assigned here as training stones for the elite special forces.
Once they could take care of the soldiers who had undergone special training, they would be able to avoid the fate of being shot. They would be recruited by the country and contribute to the country on the battlefield.
Although the criminals all knew that once they successfully enlisted in the army, they would lose their freedom in the future, at least they had regained their lives. Who knew, one day, they might be able to fight for their freedom like today?
Only criminals who had experienced the White Prison would understand how blissful it was to leave that place.
