Now, I don't ever recall an Air Despatcher hitting an a/c with a vehicle etc. This could be down to a couple of reasons:
1. They use the half chock method whenever they have a vehicle near an a/c, which is very safe and prevents this unnecessary damage occuring.
2. The 252 action and discipline on the unit was/is much more robust than the RAF. Soldiers usually have the balls to discipline people when incidents happen, something that seems to be sadly lacking in the RAF!
