Outdated or not, that's the law.
The destruction of the Van was clearly murder. If I had done that, a Marine Corps Colonel would have had his boot so far up my ass after seeing that video, that there would not be much left of me to execute.
You know what the correct response is from a CO in a situation where a van arrives to pick up bodies? Hint: It's never 'Roger. Engage.'
Your guys told you that a van arrived to pick up bodies, and they ask for permission to engage. Correct response: 'Do they have any weapons?' or 'Negative.'
Now sometimes there is so much trust between a CO and a particular guy, that clarifying information will not be asked for. This is rare, but it may have been the case here. Which still calls that CO's ability to judge character into question.
Bottom line. In the Marine Corps, there would have DEFINITELY been consequences for this action. (the destruction of the van).
Also, I noticed that the individual who said they 'had no idea how the children were hurt' was a Major. Now I know there is no way a Marine Corps Officer would tell a lie like that. They would just not say anything. You lose a lot of respect for Army Officers after seeing something like that.
