ChillDoubt - I think jake's response is one of someone who feels shocked and saddened by the death of these soldiers, and if I may suggest, has posted with perhaps text coloured by the emotion felt, rather than the facts as they are known thus far.
I do not think the military take lightly the deaths of any personel for any reason, but as advised elsewhere, by the colonel on Radio Four, and other posters on here - deaths of military personel do happen, for a variety of reasons, it is part of the acknowledged hazards of the profession.
No-one thinks it is acceptable, but a degree of reason has to be applied here.
