The Iron Star Alliance has spent a great deal of time, effort, and resources mastering the physics of field projection technologies. They rely on these fields to protect their warjacks, ships, and facilities. They also integrate these technologies into their force barriers, creating lightweight yet powerful barriers to defend friendly forces and to limit the movement of the enemy. Such mantlets also have an advantage over simpler barrier designs because as long as their field generator has not been destroyed, the barrier can always be regenerated to full strength.
