What changed
Green Book publishes free Army tools guides on the public website so Soldiers and leaders can learn how the readiness tools work before signing in.
The body-composition guide covers Army Directive 2026-13 waist-to-height ratio (WHtR) screening used by the public calculator — BMI and legacy tape methods are treated as historical context only.
Who it helps
Anyone preparing for the Army Fitness Test or height/weight screening can read the guides anonymously. Signed-in tools remain available for people who save results in their workspace.
How to use it
Open the Army tools guides hub, then choose AFT preparation or body composition. Use the linked Public Tools calculators when you want to run numbers — always confirm results against official Army publications.
