missionprep.app · FM 21-76 Field Quiz

If you got lost tonight, would your kids know what to do?

Not "have watched a survival show." Not "own a bug-out bag." Actually know — which water kills you, which berries are safe, what three fires mean, why you never run from a bear.

The U.S. Army wrote the answers down decades ago in FM 21-76, the Survival Manual. The problem: it's 233 pages of dense doctrine no teenager will ever read.

So we turned the entire manual into a game your family will fight over. And it's free — for every family, forever.

Try it right here, right now

All 24 chapters. 560 questions. Miss one and watch what happens: the app opens a built-in field manual to the exact page you needed. When you're ready, get it below and it's yours — offline, forever.

Survival knowledge has a fatal flaw: you can't Google it when you need it

Every skill in that manual matters on exactly one day — the day with no signal, no charger, and no second chances. And here's what most families get wrong:

The Field Quiz fixes all three at once: real doctrine, myth-busting wrong answers with explanations that tell you why the tempting answer kills, and a family leaderboard that makes your kids ask to study.

— THE WHOLE THING · NO CATCH —

Get it. It's yours.

Free either way — no account, no subscription, no ads, no tracking. Pick based on your device.

Option 1 · Recommended on iPhone

Install it as an app

Open the app once in Safari, then add it to your home screen. After that one visit it works completely offline from its own icon — no downloaded file to manage — and quietly picks up new chapters and questions the next time you have signal.

📲 Open the app →

Then tap the Share icon in Safari → Add to Home Screen. That's the entire install.

Option 2

Download the file

  • 560-question bank — every chapter of FM 21-76, deeply covered (as few as 19 questions in the leanest chapter, over 40 in the deepest). Each run draws 7 at random, so no two quizzes are the same
  • The in-app Field Manual — a 60-page typeset mini edition with figures. Miss a question and the book opens to the exact page
  • 161 traced study plates — real figures redrawn from the manual: the fire triangle, solar still, BLISS, COLD, snare sets, star navigation, raft rigs, shelter builds, and more
  • Family leaderboard — initials, scores, and ranks from Field Ready to Back to the Manual
  • One file, works offline immediately — on desktop and Android, no internet needed at all after you download it
⬇ Download the Field Quiz — Free

One HTML file (~660 KB). Share it with any family you want — AirDrop it, email it, put it on a thumb drive.

On iPhone: Safari has gotten strict about running a downloaded HTML file's code, so this option may open to a blank screen there. If that happens, use Option 1 above instead — it's built specifically to get around that.

Built for the family that takes readiness seriously

The content is the U.S. Army's own doctrine — the public-domain FM 21-76 Survival Manual — condensed, typeset, and drilled through 560 questions.

Questions, answered straight

Really free? What's the catch?
Really free. Download it, keep it, share it, use it in your troop or classroom. The donate button exists for families who want to support the work — it unlocks nothing, because everything is already unlocked.
What exactly do I get?
Either a single HTML file you download and keep, or an installable app you add to your home screen straight from Safari — see the two options above. Both are the same app underneath: no account, no internet needed once you're set up.
Why does the downloaded file sometimes just show a blank screen on my iPhone?
iOS Safari has gotten strict about running a downloaded HTML file's own code, so on some iPhones the file opens to nothing. It's a phone-and-browser limitation, not a broken download. Use "Install it as an app" instead — it's built specifically to sidestep this.
Is this the actual Army manual?
The questions and the in-app book are built directly from FM 21-76 (1992), a public-domain work of the U.S. Government. This project is not affiliated with or endorsed by the U.S. Army.
What ages is it for?
Written for roughly 10+ reading level. It covers real survival topics (injuries, dangerous animals, emergencies) at the same level as the manual itself.
Does the leaderboard sync between devices?
Scores live on the device you play on — which is perfect for the family tablet or a shared phone. No accounts, nothing leaves your device.
