That's ok
If you're a Vietnam Veteran who has not joined the Legion by now, you never planned on it, anyway.
The fact that any fallen soldier's photo is to be used as a marketing tool (and that is EXACTLY what this is, a marketing tool), is an egregious wrong upon any uniformed service.
Furthermore, you need to get the facts right. It is not a photo of a DEAD Marine, it is a photo of a DYING Marine; the young man was still alive in the photo, but was perishing.
