but can carry a rifle weapon in each hand. Aside from these weapons, most of the Sonic Diver units seem to be equipped with either a machine gun or a pistol as a backup weapon. In Episode 17, it is shown that the Sonic Divers are capable of independent movement. While they don't seem to be able to fight all by themselves, they can follow simple orders given to them by their pilot.Pilot suitA form-fitting flight suit that resembles a very thin one-piece swimsuit. When used in combination with a nanoskin, a data circuit is created between pilot and sonic diver. The pilot can then operate the Sonic Diver until the nanoskin degrades.NanoskinTo protect the pilot during operation of the Sonic Diver, a nanoskin gel is applied over the entire skin. This is made up of nanomachines. This coating lasts only for exactly 21 minutes and 32 seconds, but during that time the body is protected from the rigors of both flight and combat. Piloting it in the absence of a nanoskin gel is referred to as extremely dangerous and probably fatal.Delta Lock and Quadra FormationAn aerial combat procedure where a weakened WORM is surrounded by three (Delta Lock) or four (Quadra Formation) Sonic Divers. The Sonic Divers attack the WORM and sync themselves to the nanomachines that comprise the WORM's body. The nanomachines become unstable and begin to disintegrate. The WORM can then be destroyed.
