As the Hatchett cars arrived, they quickly realize that the heat inside the cars was unbearable, to combat this while the army worked out a better solution, they wrapped soaking wet canvas around the cars, this helped cool the car, and better camoflauge it in the desert. The crews also learned it was best to attack at night, when it was cool. So while Prevnan cavalry slept, The crews would accelerate, then silently coast downhill to approach the camp. The cars would easily catch the Prevnan's off guard. The Hatchett would unload into the Prevnan camp, and quickly drive away. Not only was this devastating, but it had a great pyschological affect. Seeing a giant steel monster mow down all of your friends in seconds obviously terrified the Prevnans. After hearing about the last attack made by the Prevnans, the Army is also considering sending out more cars.
