I saw this in a blog post on Slate and wanted to share it. The author is Marine Garrett Anderson:
My dead brothers will walk with me and all of the others who remember them. That is part of our service, in this our joy is shared and the important sting of their loss is a reminder to remember how different this gathering of family could be and how each one was a loss that eternally disrupts history. When I awoke the day after Corporal Michael Cohen was killed I had an epiphany that life would forever be this way. I knew he would be attached to me for every happy moment of my life, but he tells me it’s only because he wants to see too, so I let him.
