A military organization, such as that described in this article, seeks to minimize civilian casualties to the utmost possible extent. One of the realities of warfare is that civilian casualties can't always be entirely avoided, and a war still be prosecuted with meaningful hope of success. But the failure to avoid civilian casualties, however necessary, is regarded as a failure nonetheless, and weighs heavily on those involved - perhaps you overlooked the mention of an increased need for anti-suicide counseling after strikes in which civilian casualties occur. One does not often find "the complete devaluation of innocent human lives" coincident with contemplation of suicide as a potentially proportionate response to having taken them.
A terrorist organization, such as its current adversary, has no such scruples, and indeed will often seek to inflict as much atrocity on innocents as it can manage. The incentives, and the balance of advantage and disadvantage, for irregular fighters, are such that the involvement of civilians - not just as targets, but also as human shields and as a sort of moving camouflage in which to conceal oneself - is an utter necessity, because there's only one way for a stand-up fight between a regular military and a guerrilla band to end. The typical fashion in which such bands misuse innocents by default would weigh heavily on their members as well, which is why one finds such a heavy investment in ideology among these groups, whether it be religious as in the current case or secular as in the case of last century's "Communist revolutionaries". You have to have some story to tell yourself that makes your flagrant abuse of civilians seem righteous - in other words, to devalue innocent human lives enough that you can live with the things you do to them.
To casually equate such wanton violation of every civilized standard of conduct, with the extreme if admittedly at times imperfect care that military forces exercise to avoid behaving even remotely similarly, strikes me as something that must be motivated either by arrant ignorance of the facts underlying the case, or by some sort of ideologically motivated disinterest in them. Neither seems to me terribly useful in developing an accurate apprehension of reality.
