What are some good suggestions for post-Company/Battery command assignments?

I highly recommend an AS3 (Assistant Operations Officer) assignment if you have not yet had this experience. It is not a "sexy" position but will benefit your development greatly.

I asked the same question when I came out of command. I was given very similar advice, take a primary staff position at a Battalion. I believe that to be better than being a deputy at the Brigade level. I’d also consider any special programs your branch offers. I see you earned a Masters on your own, I did the same thing so I took a key staff assignment within my branch and applied for an internship (I’d consider TWI). You usually can’t apply for these broadening assignments until you have commanded successfully for 18-24 months. Something to think about, you may not have the time as a Major, between ILE and two KD assignments. Looks like you still have plenty of time before you pin Major. Good luck.

MAJ Jason Sierakowski; depends what you want to be doing and if there are any "non-career" goals in mind. Location matters to some and that drives it. It did for me. I wanted to be in the mid-west, so that's where I went. Also depends on how you did in Command. What are your chances for resident CGSC? If you are likely to go resident, are you interested in going to SAMS? I came out of command and did a year on Brigade staff and then went to the MCTP at Fort Leavenworth (then called BCTP). Then onto CGSC and SAMS. 4 years at Leavenworth. Stabilization for the family was the goal and it worked out. Do what you want to do. There are a ton of other options. You could go to the Pentagon, a service component command (USARPAC, ARCENT, ARSOUTH, etc), NTC or JRTC as an O/C, ROTC, BOLC, Captain's Career Course, AC/RC, multiple fellowships (but I assume you are out of the window to apply now if you are running to the end of your time as a commander), exchange programs with partner nations (air defense school in England...again, you may have missed the deadline for submission), and a host of other things. There is a team of air defenders here in Saudi Arabia advising the Royal Saudi Air Defense Forces right across the street from me. Tons of things to do.
