I was playing the Armed Assault Showcase. I got to the part where I had to secure the fortified roadblock before calling in the IFVs.

I kept to the right of the road. In the last covered stretch to the roadblock there is a thick stone wall that forms an "L" providing cover from the roadblock's direction and parallel to the road.

An enemy started taking fire on me with his Katiba so I used the wall for cover. Imagine my surprise when the wall toppled toward me direction under assault rifle fire! It just fell like a cartboard fake and lay on it's side. I later got shot as I lost my cover.
