Collateral damage is the deaths, injuries, or other damage inflicted on an unintended target. In American military terminology, it is used for the incidental killing or wounding of non-combatants or damage to non-combatant property during an attack on a legitimate military target. In US military terminology, the unintentional destruction of allied or neutral targets is called friendly fire.
Critics of the term see it as a euphemism that dehumanizes non-combatants killed or injured during combat, used to reduce the perception of culpability of military leadership in failing to prevent non-combatant casualties.
Every object in the scene becomes destroyable if enough of a force is applied. When exploded, objects will break down into fracture pieces that scatter around based on the blast.
