Known to blog-readers by his handle "G'Kar" (a character from the cult sci-fi television show Babylon 5) , in Iraq he was known as Major Andrew Olmsted, US Army.
When he deployed, he gave a "last post" to be published in the event of his death, to a colleague.
Here it is.
Update, 5 Jan:
- News story in Rocky Mountain News, where Major Olmsted also blogged.
