An unlawful order is one that is clearly outside the authority of the person giving it. Ordering someone to commit a crime is clearly unlawful. Killing a civilian (meaning an unarmed non-combatant, not simply someone who doesn't wear a uniform; an armed civilian is a combatant and thus a legal target) would be an example.

Resisting an uninformed officer without violence refers to the act of refusing to comply with or obstructing a law enforcement officer's authority or requests, typically during an encounter where the officer is not acting under a lawful basis or has no legal justification for their actions. This can include verbally challenging the officer’s authority or physically withdrawing from their reach without using force. Such resistance can still lead to legal consequences, as it may be deemed an obstruction of justice or an interference with law enforcement duties.
