What went into these ten pages
Written from the primary documents, not from other people's notes:
- British Army Jobs: the Army officer selection page (Briefing, Main Board, Main Board (Short), fitness levels) and the regular and reserve officer application process pages, read 21 October 2026.
- The AOSB Planning Exercise Candidate Answer Sheet (Dec 23), linked from the officer selection page.
- Every time, distance and capacity in the four exercises was worked out twice and checked against the scenario.
The scenarios are our own, not real planning exercises, and the model answers show one sound way to fill the sheet, not an official answer.
Questions
How do I get it after paying?
It's yours the moment the payment clears, and you come straight back to this page with Download and Read buttons. It stays in your ProSyllabus account.
Will the kit be updated after I buy it?
Yes. We regularly correct and improve our kits as syllabi, notifications and exam patterns change. Each time you download from this page you get the latest version, at no extra cost — so check back here from time to time, and download it again before your exam.
How do I pay?
By card on a secure payment page. Your card details go straight to the payment provider; we never see or store them. Where we support your currency, the price is charged in it.
Can I see it before I buy?
Yes. Page 1 is on this page in full, free, and the top of page 2 shows the first scenario and its map.
Is it useful for Briefing as well as Main Board?
Yes. Briefing day 1 includes a planning exercise tutorial and an opportunity to complete a practice exercise, and the assessed planning exercise is on day 3 of the standard Main Board (day 2 of the Main Board (Short)).
Does it cover command tasks or the interview?
Page 10 sets out the Briefing and Main Board programmes and gives a lecture plan, but the kit is about the planning exercise; it does not coach command tasks or the interview.
What does this kit cover?
The Army publishes an example answer sheet: problems, aims with any key deadlines, resources and transport, possible solutions (a minimum of two advised), a preferred plan in detail and a justification. This kit gives you four original scenarios in that shape, each with a map and five focused questions, and a complete model answer for each, every time worked out to the minute, with the option it rejects and why.

Disclaimer
Are these real AOSB planning exercises? No. They are our own scenarios, written in the shape the Army describes: a scenario with a map, focused questions, and the answer sheet with its six parts.
