My friends brother in law took this picture. It is from a Reserves Battalion connected to the Engineering Corps. This is a giant-tractor battalion called D9. Their job is to go in and clear the path for the incoming troops.
Before this battalion went in yesterday to Gaza to do their work, the soldiers sprayed grafitti across the whole giant front of the bulldozer shovel expressing their strong desire to bring Gilad Shalit home.
the message is "Gilad - we are coming to get you!"
