Who is the Inspector General (IG) in this structure?

• A. Major Kitty (Jiaqi) Chen
• B. Lieutenant Colonel Ethan X. Liu
• C. Colonel Ethan Xu
• D. Captain Jerry Zhang

Answer: (B)

The Inspector General is a dedicated oversight officer responsible for independent inspections, investigations, and audits that improve efficiency, compliance, and readiness across the command. This role requires standing outside the normal line of command so findings aren’t biased by day-to-day duties, and it usually goes to a senior field-grade officer who can access a wide scope of information and coordinate with multiple staff sections.

In this structure, the person occupying that senior, cross-cutting oversight position is Lieutenant Colonel Ethan X. Liu, which fits the typical level of authority and experience needed for the IG role. The other ranks shown are less suited for this cross-command responsibility within this chart: a captain is too junior, a major is plausible in some outfits but not indicated here, and a colonel would generally be a different senior position unless the chart dictates otherwise. So the officer who serves as the Inspector General here is Lieutenant Colonel Ethan X. Liu.
