BioWare has posted the necessary details on their blog. Here’s what you need to know about your missions.
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.
Successful completion of Squad-level goals will earn players a Commendation Pack, while victory in the Allied Goal mission will grant you a Victory Pack.
