Command and Control Operations (C2OPS) Block 1 Practice Test 2026 - Free C2OPS Practice Questions and Study Guide

In Air Force specialty codes, the level you’ve achieved is shown by the level digit in the code. The sequence goes 3-level, 5-level, 7-level, and then 9-level. The 9-level represents the highest skill level and indicates the airman has demonstrated a high degree of knowledge and mastery in that specialty. So the code with the 9-level marker shows the top of the progression, making it the best representation of the highest skill level. The other options reflect lower levels (3-, 5-, or 7-level) and do not indicate the maximum.
