Ep 3. Casualties of War

PJ's unit in Syria attacks the ISIS-held city of Al-Shaddadi, but heavy combat evades them once again; a frustrated PJ heads home to the States, leaving Levi and the others behind; Jeremiah seeks to do the opposite, as he misses war and is desperate to return; and all the volunteers do their best while joining Pete's medical team in preparation for the impending siege of Mosul in Iraq, but it soon proves fatal for one.
