Hey guy, thanks for the responses. I've had a think about this and in my mind I rationalise combat as follows. In a dog fight it is kill or be killed which is basic survival so I'd have no problem with this. If I was dropping a bomb on an enemy target and the sovereignty of the UK was at risk then again, I'd have no problem with this. However, I'm not sure how to rationalise dropping a bomb on a Taliban target - I know they are thought to be responsible for worldwide terrorist attacks but it seems difficult to rationalise (what I mean is that the sovereignty of the UK or my life is not directly at risk). How do pilots who are serving in Afghanistan rationalise this?
