On the nuke side, there were a few LTs who were showing up as Principal Assistants (like a Dept Head); they were frocked, and I guess it made sense since they typically had a few junior O-3's subordinate to them.
The frocking will not really help you career wise (promoting), other than you can get a fitrep bullet that says something like "already an outstanding performer at the O-4 level". So, I personally would not factor that (either way) into your decision. Plus, the fact that the nuclear program does it is sort of an automatic (-1).
Plus if you are frocked early, you just become cannon fodder for the senior Hinges...
Interesting article. Still never seen it done even with guys on the select list and filling a O-4 billet. Seems like something that would apply more to the O-5 and above crowd.
This is a joke right? It hurts my soul that anyone would ever consider joining the shrub club any sooner that absolutely necessary. Why not fill the billet and continue wearing LT ?
Take it from a dirty hinge - don't rush this. And that's not just some "hinges suck, JOPA rules" cliche... What job are you considering that is SO important that it requires you to be frocked (which in most cases is a no no for officers). Looking at your somewhat vague profile it appears that you're nearing the end of your shore tour (maybe already complete with it). This makes the interest in rushing O-4 more curious.
It's a job at a joint command HQ. People don't take you very seriously here as an O-3.
