The display on top of the bus top will slide horizontally almost like a treadmil to represent motion.
There will be a 45-degree top-down view of someones legs running. As they run they drop their war gear, e.g:
military backpack, their weapon, helmet etc... Hopefully people will understand that this is a soldier dropping
his gear.

Eventually the camera will rotate to a silhouette of London showing the person running towards the city,
"coming home"
