Exo-Frames

Exo-Frames or E-Frames for short were created by humans in their effort to terraform and colonize Venus and Mars and to protect themselves from any possible aggression from outside of the Solar System. They can be thus divided into two main categories — civilian and military models. However, since the series primarily described the Neosapien War that followed the Second Neosapien Revolt, nearly all E-frames shown in Exo-Squad were battle machines. Another distinction is that between human (Terran) and Neosapien E-frames.
Originally, all E-frames were humanoid exoskeletons (hence the name), but after several decades of extensive development non-humanoid E-frames vehicles based on the same technologies have been introduced. By the time of the Second Neosapien Revolt, all machines steered directly by one or two pilots were considered E-Frames, regardless of their type, purpose or design: walkers, tanks, space fighters, bulldozers, etc.
A common feature of all E-frames is a sophisticated neural interface that backups "normal" manual steering: each pilot had to undergo surgical implantation of a "cyber socket" to the back of one's neck that allowed direct control over the E-frame via a "cyber jack". Since the brain patterns of humans and Neosapiens are slightly different, E-frame interface has to be reconfigured depending on the genetic race of the pilot. All E-frames are powered by fusion packs. Civilian fusion packs generate much less power than military ones, while the latter are (if intelligently applied) a potentially devastating explosive.
After Professor Algernon joined the Exofleet, some of his inventions were implemented into the Able Squad's E-frames, making them truly unique (so-called Algernon Upgrade).

Trivia

• We can probably assume they have more complete seals than the Toy-based TV show demonstrates, otherwise a lot of frames are not space capable, and dangerously exposed.
