The HCS have despatched an extra 3 brigades, 1 armoured, to join the 2 already on the planet as well as 2 air regiments, the 132nd Air Defence (a F-40 unit) and the 229th COIN (A-85). All of those forces have been "invited" by the Clone government on Oscar to help in protecting "Clones and humans" from insurgents.
Not that there is much insurgency at the moment, there have been sporadic attacks by OTA units on Clone positions but in at least one of these incidents the OTA unit had been cut off from communications and didn't know there had been a ceasefire for months!
920 humans have applied to leave Oscar and 1000s more are thought to be considering it. The HCS have allowed the DDS to bring a transport into Oscar orbit to help in humanitarian work, a Provider is on the way.
