Any word on the identity of the sailors? Or their rank and rates?
From the details of what happened, I'm guessing they weren't corpsmen or special warfare. They were probably Individual Augmentee (IA). There's a lot of this these days. IA sailors are ones that for whichever bit of bad luck came their way, they were selected to go to Iraq or, most commonly these days, Afghanistan. Prior to deployment, they're sent off to Ft. Bliss or some other INCONUS training installation and given a very abbreviated lesson in soldiering. Then it's off to Afghanistan were they provide behind the lines administrative support that frees up the Army and Marines for combat duties.
As far as I know, no IA sailors have been KIA yet. Navy combat deaths have tended to be limited to corpsman and special warfare but I could be wrong. This might be a first.
The IA’s usually train at Ft. Lewis, WA depending on what their mission “in-theater” is going to be.
