It appears that the fights in question occurred between April and June....that's the nearest I can tell from the news articles I have seen.
What we don't have is a description of those battles at that time. I haven't found a single article on the subject.
What we need is some description of what was going one:
1. We need it from the perspective of each of the young troops involved.
2. We need it from the perspective of other unit members.
3. We need anything written by any investigators, reporters, or witnesses.
Even without all these things, I will automatically side with our troops, because (1)they are in the middle of a war and deserve the benefit of any doubt; and (2) our system says they are INNOCENT until PROVEN guilty.
The one bit of info that we do have that troubles me is that they are accused of planting AK47's on the bodies. As everyone knows, our troops don't have AK's; they aren't allowed to "save" AK's, but have to turn them in; and AKs aren't just lying around everywhere, easy to pick up anytime on wants one.
In short, they got those AKs during a battle/fight, and it makes most sense that they got them during that particular battle/fight. Did anyone even bother to check if they'd been fired?
