How do you get the position of "social liaison" in the U.S. military?

Well, it's just not actually a position.

It seems that Jill Kelley, the other other woman in the unfolding Petraeus scandal, acquired the honorific via media reports struggling to describe her ambiguous volunteer role as a popular hostess to Central Command’s military elite....

“There’s no such thing,” one officer told us. The made-up title appears to be a polite way of saying “rich Tampa socialite who likes to hang with four-star generals.”

I thought of some other things it would be a polite way of saying, but I won't mention them. I'll just suggest that the officer is only portraying the women in a negative light. What about the generals? The women couldn't have made any progress in the role of "social liaison" if the generals didn't want to be liaised. What the hell are these men doing appropriating the power and prestige of the United States military for the purpose of liaising with women-of-a-certain-type? These are the men who send enlistees into battle, who demand sacrifice from idealistic young Americans. They should not be flaunting whatever pleasures they pursue.

And by the way, how does one get the position called "socialite"? It's not as though that's anything more than a characterization of what someone appears to be doing. Wikipedia says:

A socialite is a slightly pejorative term for a member of a social elite, or someone aspiring to be a member.... A socialite participates in social activities and spends a significant amount of time entertaining and being entertained at fashionable events....

American Members of The Establishment, or an American "Society" based on birth, breeding, education, and economic standing, were originally listed in the Social Register.... Members of true "society" were distinguishable from members of post World-War I "cafe society," from whom are further distanced "socialites," who are considered aspirational members of true "society," but with no substantive social credentials or personal achievements.

You never hear about true "society" anymore. Only the pretenders get any attention now. But what are they pretenders to? To nothing!

I've got another question: Do identical twins tilt their head sideways the same way at the same time? Because that photograph is driving me nuts.
