The HCS has already announced extra forces to be deployed to Petric but since the attack on a HCS Cosmos class cruiser a short while ago more forces have been ordered there including a squadron of Molentic Tuul cruisers (5 ships) and 2 Soulakis.
Land forces have already begun to arrive on the planet, up until now a backwater of the empire, though the bulk of the 15th Legion which has been reassigned to the planet will not be in place until next year.
