What do you call the murder of civilians in war? Collateral damage

And what do you call a failed Army which never was an army but was a collection of warring gangs and factions which had nothing in common, and which answers to various paymasters? You call it: "a decentralized insurgent brand".  And what do you call US special forces when they appear--in violation of international laws and agreements governing wars--without their military uniforms and disguised as local natives? You call that: "relaxed grooming standards".
