An ground use ExoShell that was developed from the ExoS-002 "Zaku". As such it is more durable then even the then newer ExoS-003 "Wagtail" and even the current ExoS-006 "Wagtail II". Its armor is a complex matrix of composites designed to absorb/disrupt sensor scans. Its passive enough that the missing data turns up as a glitch to the enemy system. While its a weaker armor then the standard its also lighter, allowing for more of it and for it to be thicker. The end result being that the unit is still heavily armored.
