I haven't been a recruiter for a number of years but still need to accurately enter and transfer information on Soldiers regularly. One thing I have never seen guidance on is the ASVAB data fields on the ERB. The old DA 2-1 listed each by their historically known names: GT, GM, EL, CL, MM, SC, CO, FA, OF, ST. However, the version ERB used presently mostly gives names, but a few are identified by their old two letter field. They are: GT, ADMIN, CMBT, ELEC, FA, MECH, FOOD, COMMO, MAINT, TECH. Not all entries on military forms use the fields, they are still using the old ones. I have looked for documents that clarify these fields but have only found the assumption that it is clear. This is the issue I am bringing to anyone that cares to set me straight. While some of the listed ERB fields seem obvious, I think it is possible to incorrectly input scores for SC, ST, and GM. Which are your COMMO, MAINT, TECH scores?
