Why Doesn't Anyone Impersonate Submariners?

For those readers who don't stray outside of the submarine side of the blogosphere, there's been a major blogswarm the last couple of days regarding a video put up by someone named Jessie MacBeth, who was claiming to be a Ranger who "admitted" commiting horrible war crimes in Iraq. In short order, the glaring inconsistencies in his story caused it to blow up in his supporter's faces. Most of the background can be found here and here.

A "blogswarm" is when a large number of blogs all start talking about one controversial issue; it's a very effective way of getting lots of dedicated people figuring out what the "ground truth" is. The blogosphere is fairly self-correcting, even across partisan lines; in this case, it only took a day until even the "progressive" sites were distancing themselves from the MacBeth claims, due mostly to the great detective work done by a large number of milbloggers, especially at Milblog Ring HQ. Lately, I've been interested in how these blogswarms get started. In this case, I'm pretty sure I can identify the initial post that got the milbloggers all working on the issue: it's right here. (Of course, I'm not pointing it out to blow my own horn; it's strictly to aid future pop-culture historians researching the blogswarm phenomenon. I knew my early morning scans of Democratic Underground would pay off someday.)

Back to my initial point: why don't we ever see anyone impersonating a submariner? Submariners are cool; they make movies about us! Maybe we don't have the notoriety of SEALS and Rangers, but chicks still dig us. It just doesn't seem fair...
