With a sloooooooooooooooooooowwwwwww connection, I've not had time to look at the footage yet - but from the discussion it sounds remarkably similar to an mpeg of a tractor being shot up by an AH-64 that was doing the rounds in January (it was discussed on the army means that dare not speak its URL).
If it is the same, it would seem that either a) the Mail is very, very slow or b) that there is an element of bandwaggoning [is that a word?] going on.
Can anyone confirm whether it is the same footage? If it isn't, farm labouring in Iraq has become vastly more dangerous...
