Target: Earth (Veil of Doom 1) - S1.E6

After 1 year in the brig for insubordination, Able Squad is back in action. Marsh, Marsala and Deleon get the first mission - to return to Earth and disable the newly built planetary defense shield with the help of the Earth resistance. But when they're ambushed at the rendezvous point, people start suspecting there's a traitor in their midst.
