Meaning Physical Augmentation Gear, they are a powered exoskeleton developed by the EDF to use against the aggressors.

The gear is powered by Energy Core which provides the wearer with superhuman abilities. The EDF has successfully developed a number of PA Gear which when worn, give the soldiers a variety of fighting abilities.

A strange gem embedded within the aggressors which is capable of producing a vast amount of energy. It is believed that these energy gems is what sustains the enormous bodies of the aggressors.

The EDF were able to retrieve an energy gem and process it into capsule form, to use as a source of energy for PA gears, weapons and base facilities. Many fossil fuels and energy facilities were taken away from the humans which has made the energy core an invaluable form of energy for the EDF. Although the enemy, the aggressors' energy gems are what keep the EDF going.
