Although not officially there it was common knowledge that DDS special forces known as Prowler units have been operating on Oscar to support human insurgency operations against the CAO and HCS. Now however it is thought that Prowler units have withdrawn from Oscar along with several dozen human insurgents.
There are two reasons for this, one is the upcoming vote on Oscar joining the Clone Star Empire which is expected to be positive for unification and second is that is insurgency was becoming increasingly difficult to maintain with much of the human population having left Oscar already for relocation on nearby New Jakarta and large HCS forces arriving.
With the Prowlers now left it is expected the HCS may withdraw some units from Oscar after the vote has taken place. Space forces have already been lessened in an attempt to defuse tensions with the DDS.
