SAU-Standard Articulation Unit
It wasn't until 6 years after the first Breather was built that an actual SAU could be finished and issued into combat. The SAU features a similar micro nuclear system as the AMMSR in that it uses thorium salts to fuel the reaction but since reverse engineering one wasn't an option Nine Corp decided to develop their own version of the AMMSR and the result was a similar, larger version with a much higher output than the AMMSR. However it is the size of four AMMSRs it has 30% the output that four AMMSRs would have while being a similar size. Unfortunately the Nine Corp version could not be reduced in size so it is restrained to larger and more expensive models of SAU.
