While Ross is back in the UK three soldiers from B Company are killed in a tragic blue-on-blue accident.

On the 23rd August Privates Aaron James McClure, Robert Graham Foster and John Thrumble died when the air support called in to help defeat the enemy hit the compound in which the three were engaging the Taliban from.

Eight days later Ross returns to the frontline to be with the men of B Company and 7 platoon. We tell the story of how the men were affected by the attack. The families have given us exclusive access to video footage showing the moments before, during and just after the bomb destroyed the compound; and we talk with the men who tell Ross how they feel about what has happened.

Ross joins the fire-support group as they attack Taliban positions and re-assert their dominance of the area since the blue-on-blue attack. This is just one-half of the operation.
