Miliaris type drones have been used in a half-dozen attacks on the core worlds of the Clone Star Empire. Drones attacked a Clone Naval Air Service base on Cloneworld, and a Clone Army communications relay station. Minor damage was caused to the latter.
On Sandworld two oil fields were attacked by drones, causing a large fire and an explosion which resulted in casualties. There were also two attacks on Lomar, one is thought to have been against the Clone Defence Forces HQ on the planet though this failed, the other was against a major communications antenna which caused enough damage to knock the transmitter out of action.
No one knows who is causing these attacks on core CSE worlds. No Eritrans live on these planets, it is suspected it could be organised by CDF elements opposed to Admiral Anderson.
