Two helicopters are attacking the rebels, and at their altitude they would see and be able to attack anything approaching on the ground. Despite this, Miles and Rachel arrive on a wagon with several weapons.
A helicopter finally fires a rocket and it knocks down Miles. Both helicopters then cease firing while others on the ground tend to Miles. In reality, rockets would have been used earlier and both would have pressed the attack once Miles was down.
When Rachel, the mother, and Ben, the father are about to see their son taken in for major surgery, Rachel leans down to comfort her son and tell him that she loves him. Her son's name is Danny. This is a well known fact through the entire run of the show's history. In this moment though, she calls him Ben, which is the name of her husband.
