Listen for what the group needs
AOSB Briefing includes a group discussion and practical leaderless tasks, according to the Army's current officer assessment guidance. A candidate who talks constantly can prevent the group from using its best information. A better question is whether your contribution moved the work forward: did it clarify the objective, test an assumption, make space for a quieter member or bring the group back to a decision?
Build on an idea before competing with it
Civilian groups give you plenty of practice. Try restating another person's suggestion accurately before proposing an alternative. Where you disagree, explain the cost or constraint rather than judging the person. Someone may still have the better answer. This demonstrates the ability to reason together; memorising a 'leadership phrase' tends to collapse as soon as the situation changes.
Watch the clock without becoming the clock
A time constraint matters, but announcing the remaining time every minute is not the same as leading. Agree what must be decided, identify information that is missing and propose a practical next step. In a peer-led group, you can help with structure without appointing yourself commander. Each intervention should have a purpose.
Separate initiative from control
Leadership under observation is not an acting competition. Sometimes initiative means summarising three opinions fairly; sometimes it means recognising an unsafe or impractical proposal; sometimes it means stepping back because another person has expertise. Practise noticing those moments rather than rehearsing a single character for every task.
Keep the rehearsal authentic
Use harmless civilian exercises and ordinary discussions. Do not ask anyone to disclose confidential employer information or reproduce military assessment material. Only the Army decides how its actual tasks are evaluated.
Try this independently
Organise a four-person discussion about a fictional community project with a limited budget. At the end, ask each person which contribution improved the decision and which one created confusion. Compare the answers with your own memory.
