Despite highly advanced weapons being deployed in the battlefield, retrofitting old rigs is still the most efficient and cost-effective way of warfare. APCs from the early 21st century made up the vast majority of these refurbished battlefront machines.

The rail gun requires extra power so cables have been rerouted to additional batteries at the back of the vehicle. Old dogs can learn new tricks.
