Well gentlemen, as I said I am not an IntO and I will now bow down to Beag's superior tractor recognition. I found a longer piece of video on the internet, from which the aformentioned clip is taken. If you have broadband and file sharing software search for a video file entitled 'Apache kills in Iraq' (36MB).
Yes I was wrong the AAA is a tractor and the thing below it is a furrow. However, before the Mail clip kicks off you see that the chaps are up to no good, moving weapons into the field from the truck.
The American (and allegedly the Brits') handling of Iraqi POWs recently has been deplorable and I feel this article is just trying to jump on the bandwagon.
I still think that this particular article is a non-story.
