Army Armor Handbook

The Combat Arm of Decision.

Mounted-force doctrine that works at the motor pool, in the field, and anywhere else the bars run out. 32 publications carry their complete text — 1,648 sections and 422 figures — including the tank platoon, cavalry squadron and combined arms battalion manuals in full.

WHAT'S INSIDE, IN FULL TEXT
• ATP 3-20.15 Tank Platoon — formations, movement, and the engagement process
• ATP 3-90.5 Combined Arms Battalion
• ATP 3-20.96 Cavalry Squadron — reconnaissance and security operations

A further 84 armor and cavalry publications are cataloged with links to the official PDF, giving a 116-publication branch library.

Every manual, every chapter and every figure is free to read — no account, no ads, no trial.

BUILT FOR THE FIELD
• Search the full text of every embedded manual in one pass
• Figures, org charts and tables render inline and zoom to full screen
• Bookmarks and favorites survive between sessions
• Import your own PDFs and index them with the doctrine
• An optional AI assistant grounded in the manuals. The on-device model needs no account and no connection once downloaded; bring your own Anthropic or OpenAI key if you would rather use a cloud model.
• Nine languages: English, Spanish, Portuguese, German, French, Hindi, Indonesian, Japanese, Korean

No ads, no account, no tracking, and nothing to download again before you can read.

WHAT THE UNLOCK ADDS
The study tools are a single one-time 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.
