Accuracy standard

Military lane: aligned to publicly releasable Marine Corps T&R material, including current NAVMC 3500.56C and NAVMC 3500.124A w/Ch-1. Unit SOPs, current technical publications, access authorizations and the actual Annex K/OPORD always govern execution.

Civilian lane: certification guidance is mapped to current vendor objectives and is labeled by skill level, so a beginner is not dropped into an advanced credential first. Last content verification: 9 Aug 2026.
