Pre-Enlistee BMI and PES BP: Obese BMT Guide
BMI is one of the few pre-enlistment numbers people can calculate before CMPB sees them. That makes it useful, but also easy to misuse.
CMPB's public material links BMI to basic training planning. The pre-enlistee IPPT and BMI page says that if BMI exceeds 27.0, basic training duration will be 19 weeks. CMPB's PES-based BMT page also describes PES BP as obese with BMI more than 27.0. Those are important public markers, but they are not a substitute for medical screening.
This guide explains how to use BMI as a planning signal without pretending it is a final PES or MCS decision.
