Isolator or Iso­shields are a kind of force­field bubble that is selectively permeable to the atmosphere, temperature and nanosphere where present. Large, static devices can create isolation zones encompassing entire buildings. Smaller, mobile machines have a correspondingly smaller field size. Iso­drones are general purpose drones fitted with mobile iso­shield generators.
Iso­drones are heavily protected by kinetic armour as well as substantial nano­cored casing.The iso­shield creates immense gravitational resistance that makes it impossible for the drone to move very quickly. As a result, the iso­drone is a sluggish machine that moves only slowly, ideal for protecting exposed troopers.
