I am trying to find out how to re-class to a 40A, but am having trouble finding the correct first step. Would anyone be able to assist?

MAJ(P) Deoki (FA40 branch manager) is the guy that you want to speak with. Send any questions and I will try and give you an honest cut.

Adam, I just sent you an email which is one I send when anyone asks about being a FA40 (which happens pretty regularly). I see your original question was a little different. If you are active duty, you transfer into FA40 through the Voluntary Transfer Incentive Program which occurs twice a year. Watch for the MILPER messages. The MILPER for the most recent VTIP was MILPER 18-070. If you want more information on VTIP, HRC has an informational page at https://www.hrc.army.mil/content/Officers%20Voluntary%20Transfer%20Incentive%20Program%20VTIP Basically, your YG and basic branch have to be allowing officers out of the branch, and FA40 must be requesting officers (IN/OUT calls). You will submit a packet and compete to be accepted into FA40. Numbers of applicants and number of selectees vary greatly from VTIP to VTIP. My year there were 25 applicants and 5 were selected. Two VTIPs ago, we took 31, this last one, we took four. The most important thing you can do to position yourself for selection is to have very strong evaluations. The packet may be different now, but when I was going through the selection process it was a 4187 that I signed, an ORB, my last 5 OERs, and a MFR stating why I believed I was qualified for acceptance. I would not worry about not having a STEM degree, most of us don't. Please don't hesitate to reach out to me if you have any other questions.

Contact the FA40 Assignment Officer in HRC. He knows the process...
