The EATADIK line

Pick your field

Same no-BS method, every field with a high-stakes test. The Army edition is built and releasing now — the other five branches are working through the same pipeline behind it.

● Releasing now

Army

Twelve titles built: three levels of board prep, plus Selection, Ranger School and Sniper School — each with a companion field reference. 11,050 Q&A, every card cited to current Army doctrine.

The other five branches

Navy, Marines, Air Force, Coast Guard and Space Force are scanned and moving through review. We publish a branch when the whole branch is right, not one title at a time.

Survival

Field references for when the plan stops working. Survival Essentials is built; urban, cold-weather, desert, jungle, water and disaster volumes are next.

Aviation

FAA knowledge-test prep built from the official handbooks — written by a pilot, not a test-prep intern. Source material is scanned; decks are in review.

Maritime & licensing

USCG deck licenses and the civilian tickets that gatekeep a raise. Sourcing first — nothing ships until the doctrine behind it is verified public-release.

Trades & civilian certs

CDL endorsements, first-responder certification, real estate licensing and citizenship prep. On the roadmap, not yet in production — we'd rather say so.

Why it works

The method

No filler, no rephrased internet trivia. Just the questions that actually show up — drilled the way memory actually sticks.

01

Straight from the source

Every question pulled from official, publicly released manuals and doctrine — citation included, so you can verify us.

02

Cover & quiz

Question on one page, answer on the next. Cover, test yourself cold, flip, repeat.

03

Decoded acronym glossary

Not a list — a decode. The front section every soldier needs cold, in every single booklet.

04

Print & digital

Paperback in up to three trims, hardcover, and Kindle. Study anywhere.

Who wrote this

Not a test-prep intern.

AUTHOR PHOTO
(flight line or field — not a stock suit)

EATADIK is written by Jeffery Alexander Smith — U.S. Army veteran, Cavalry Scout and Sniper, who stood the promotion boards these booklets prep you for. He went from answering board questions at parade rest to flying as a pilot — and built the study line he wishes someone had handed him.

"Every card cites the pub it came from. If you can't verify it, you shouldn't memorize it."

Every booklet: sourced like a staff study. Written like your squad leader.
