Army Infantry Handbook

Follow Me.

The infantryman's reference library, on your phone, with no signal required. 26 publications in the Infantry library carry their full published text, taken from the official Army PDFs, with more than 550 figures. The Ranger Handbook, the rifle platoon and squad manual, and the marksmanship and land navigation references are readable in a training area with airplane mode on.

Not a government app. This is an independent reference, not affiliated with or endorsed by the U.S. Army or the Department of Defense. Every publication in it comes from the Army Publishing Directorate, the official source for Army publications approved for public release, and no other source is used:
• Army Publishing Directorate: https://armypubs.army.mil
Doctrine is revised regularly, so check anything operationally significant against the current official version.

WHAT'S INSIDE, IN FULL TEXT
• TC 3-21.76 Ranger Handbook: patrolling, battle drills and fieldcraft
• ATP 3-21.8 Infantry Rifle Platoon and Squad
• TC 3-22.9 Rifle and Carbine
• FM 3-25.26 Map Reading and Land Navigation, the 2001 edition with its 102 figures (its successor is not approved for public release)
• FM 7-22 Holistic Health and Fitness, the Army's physical readiness doctrine
• ATP 3-21.90 Tactical Employment of Mortars
• ADP 3-90 Offense and Defense, FM 3-90 Tactics

Another 77 infantry publications are cataloged with direct links to the official PDF, for a 103 publication branch library in all. Older editions, such as FM 3-21.8, open the official PDF and name the current manual that replaced them. The whole Army catalog of 341 publications is one tab away.

Reading is free: every embedded manual, every chapter and every figure, with no account, no ads and no trial.

BUILT FOR THE FIELD
• Full text search across every embedded manual at once
• Chapter and section navigation, with figures you can pinch to zoom
• Bookmark a section and mark a manual as a favorite to return to it
• Import your own PDFs, such as SOPs and unit references, and index them alongside
• An optional AI assistant that answers from the manuals themselves. It runs a model on your own device once downloaded, so it needs no account, no subscription and no connection. If you already have an Anthropic or OpenAI key you can use that instead and pay your provider directly.
• The app itself speaks nine languages: English, Spanish, Portuguese, German, French, Hindi, Indonesian, Japanese and Korean. The manuals stay in English, as the Army publishes them.

No ads. No account. No tracking. The manuals are on the device.

WHAT THE UNLOCK ADDS
The study tools are a single purchase, not a subscription: full text search across every embedded manual at once, bookmarks that survive between sessions, importing and indexing your own PDFs, and the AI assistant.

LEGAL
Every publication in this app is a U.S. Government work in the public domain under 17 U.S.C. § 105. Army branch insignia and related marks are property of the U.S. Government and appear here for identification only.

This is a study and quick reference aid, not a substitute for official publications, unit training, or command guidance. Verify currency through official channels before operational use.

Recent changes:
Manuals that earlier versions condensed now carry their full published text, taken from the official Army PDFs. Where the Army has replaced a manual, the current edition is embedded, and the older one opens the official PDF with a note naming its successor. Several manuals now show their figures. The AI assistant now builds its answers from passages in the manuals and checks each answer against them before showing it.
