Source extraction notes
The DMDC crosswalk records skill-level validity windows, not personal service dates: helper, apprentice and craftsman records begin in October 2001, while the journeyman entry begins in October 2007. All end in December 2011. AFPC release 111 of 30 April 2012 explicitly identifies the January 2012 change from 2A3X1 to 2A3X4, Fighter Aircraft Integrated Avionics, including aircraft-specific suffixes and CV-22 coverage. The article does not provide an exact January day.
