“Anyone know what an E-10 (or whatever his rank is) makes per month? My guess is that it’s a whole lot more than what an E-4 makes.And maybe even more than an O-3 makes. “
No such thing as an E10.
Having risen to the lofty rank of SP5 (E-5) during my stellar Army career I'm unfamiliar with those in the stratosphere.;-)
Army-wise,a Master Sergent (three up,three down) is an E-8.Then the various Sergents Major,I assume,would be E-9 so I assumed (or suspected) that the top Enlisted Man in the services would be E-10's.
I was wrong.
