Echo base defense

After the shield generator was destroyed, the rebels retreated to the hanger and are using crates and a snowspeeder wing as cover from the snow troopers.  Outside the hanger, the snow troopers are advancing towards the rebels. One of the troopers has a rocket launcher and is destroying the turrets.  Inside the hanger Han and Chewy are helping a group of rebels defend their position and some pilots escape from the action. The wing they are using was taken from a snowspeeder that was being repaired when the attack came.
