Your comments are quite uncalled for. The basis for your uninformed observation is, again, a thoroughly foreshortened and heavily edited video clip, taken totally out of context. You need to see the whole engagement and feel the adrenalin when a missile warner is growling in your ear so the "armchair" riposte is actually a fair comment.
A 2/3 man SAM Crew can wreak havoc and who is to know which coalition aircraft would have been taken out if these three "farmers" had been ignored. Very little farming is done in the dark in the wee small hours and the TI Video clearly shows the second target scrabbling under the "tractor" to unwrap the hessian from his weapon. You don't see him go to ground by the way - he was well trained.
I wouldn't have left them behind to shoot at my oppos.
