Ranger Handbook — Interactive Field Toolkit & Reference
The complete U.S. Army Ranger Handbook (TC 3-21.76, September 2025) — every chapter, figure, and table — plus interactive tools that turn the doctrine into something you can drill, calculate, and quiz yourself on. Built for RASP candidates, Ranger School students, ROTC cadets, and any leader who needs it cold.
The handbook and the practice quiz are free. An optional one-time $0.99 unlock adds the field calculators, request builders, the full Creed Trainer, search, and bookmarks.
No ads. No data sharing. No subscription. One optional one-time purchase.

FREE — QUICK ACCESS WHEN IT COUNTS
One tap to MARCH, 9-Line MEDEVAC, Call for Fire, TLP Steps, OPORD Format. The things you'll actually pull out the phone for.
FREE — FIELD-READY
• Fully offline — no signal, no problem
• Dark, low-light interface
• Pinch-to-zoom on every figure and table
• Try Stanza 1 of the Creed Trainer free in any mode
STUDY TOOLS UNLOCK — $0.99 ONE-TIME
Interactive tools an e-book can't give you:
• Field calculators — pace count, mil-relation range estimation, and back-azimuth / grid-magnetic conversion
• Request builders — fill in and share a formatted 9-Line MEDEVAC, Call for Fire, or SALUTE report
• Full Creed Trainer — all 6 stanzas in Study, Recite (scored), Cards, and Fill-In modes
• Handbook search — find any topic across every chapter
• Bookmarks — save sections for one-tap access
FIGURES AND TABLES INCLUDED
All 143 source figures — formations, battle drills, knots, ambush diagrams, range cards — extracted directly so they match the printed handbook. 15 reference tables covering machine gun specs, mortar and artillery capabilities, radio characteristics, demolition explosives, and evacuation precedence.
SOURCE TEXT, NOT A REWRITE
Every section includes the verbatim TC 3-21.76 prose alongside scannable quick-reference summaries. You get both — the doctrine as written, and the key points distilled for fast lookup.
A study and reference tool. Always verify against current published doctrine.
