These soldiers should get a medal and a promotion.
And more ammo, too.
For what, assuming that the charges are true? Illegally killing detainees? Threatening to kill a subordinate for reporting your crime? Both of those are despicable activities, especially for the NCO involved.
A soldier may not like following the rules, they may not agree with them, but they are the rules they agreed to follow when enlisting. Killing detainees that pose no threat to you is against the rules. It's also immoral.
