Similar law in Norway IIRC. The idea is essentially to put you (the soldier) in the situation where being threatened with punishment for disobeying the order is weighted up against the threat of punishment for obeying an unlawful order. Basically, if you’re given an order you honestly believe is illegal, it’s a lot easier to stand by a decision to face the consequences of disobeying it if you know that following the order can lead to the same, or worse, consequences.







I’m know little about the details around how it works in the US, but I think saying
Is a bit of an oversimplification. The point is that if a soldier will face consequences for disobeying an order, but no consequences for obeying an unlawful one, they have no dilemma (outside their own morals) when faced with an order they believe is illegal. Furthermore, they can be coerced into doing things they know is wrong and illegal. By putting this into law, you force the soldier to face the dilemma that if they truly believe an order is illegal, they can be punished for following it. That gives a much stronger incentive to actually stand your ground when ordered to do something that makes you think “there’s no way in hell that this can be legal”. It also removes or diminishes an officers power to coerce soldiers to do something they know is wrong and illegal.
Regarding
there’s probably some minor cultural differences between armies here, but by and large you’re probably mostly right. However, I don’t think it’s right in extreme (think, genocide) circumstances. A lot of these laws came in place post-WWII, and are formulated with the knowledge in mind that soldiers can and have been ordered to execute civilians and shoot at unarmed protesters. I’ve been a soldier myself, and would definitely question an order to open fire on unarmed civilians. I hope most other soldiers would do the same.
