The ideal training ground would be a place where an instructor could control absolutely everything, create trials at will, change the number and shape of objects, and even manipulate the weather.
This used to be impossible, but with the technology available at the Citadel, it was no problem. In fact, the military trained not only at training grounds and in camps, but also in virtual chambers, where an instructor created the necessary obstacles for them.
Even for Phantoms, this was effective — but only for the weakest ones. When Adam first became a Phantom, he trained in that chamber before heading out on his first real mission.
But now, as a K4-Phantom, it was too dangerous. The virtual chambers were simply high-tech simulations. No energy was involved in the process.
