Documented history

Pavements Maintenance Specialist

The report gives 31 October 1993 as the creation date for 3E2X1. May 1996 is the report's publication date.

  • The consolidation is inferred from comparisons with both predecessor specialties; the conversion statement does not explicitly name both codes.
Source extraction notes

The official report states AFSC 3E2X1 was created on 31 October 1993 during restructuring and compares it with the predecessor 551X0/551X1 ladders, evidencing their consolidation. Confidence: medium because the conversion sentence says 'this AFSC' rather than listing both predecessor codes inline.

Source-stated predecessor pattern preserved; merger applies at the 9-skill level.
