CHAPTER TWO

  The Personal Defence Suit (PDS) is the standard set of clothing, camouflage and tactical armour in one comprehensive package for use by CMC Marines. It can be easily augmented with a zero gravity manoeuvring pack or sealed for operations in limited atmospheres. It is lightweight and covers the entire surface of the individual. In trials, the armour has sustained damage from thermal and kinetic energy weapons and been able to operate even after sustaining over fifty percent damage. Variants such as the Combat Engineer Suit (CES) feature thicker armour, powered tools and augmented strength for use in the sapper role.
