BioWare is trying to keep Mass Effect 3 owners engaged with yet another multiplayer event. There is not much else to say than this:
Operation: VIGILANCE (September 7th-9th)
Unexpected attacks have taken out several squads and damaged vital Alliance equipment. We will deploy drones to repair damage and investigate the nature of these attacks.
Squad Goal: Complete up to and including wave 10 on any difficulty without using a consumable (medi-gel, ammo, Ops pack or Cobra missile launcher).
Allied Goal: Complete 250,000 escort missions on any difficulty.
Special Circumstance: None
Squad Goal Success: All individual players awarded a Commendation Pack
Allied Goal Success: All players awarded a Victory Pack
