College of Policing • Briefing

IIMARCH police meaning

Briefing model (College of Policing APP / JESIP). A quick, source-backed reference for the UK policing mnemonic IIMARCH.

Short answer

Structured briefing format used once commanders have made decisions and need to relay the plan so it can be understood and actioned. College of Policing APP presents it as a briefing structure for operations under gold/silver/bronze direction; JESIP adopts the same headings in its joint-doctrine briefing tool.

Legal anchor: College of Policing APP: Operations — Briefing and debriefing; JESIP Joint Doctrine — Briefing

When officers use it

Structured briefing format used once commanders have made decisions and need to relay the plan so it can be understood and actioned. College of Policing APP presents it as a briefing structure for operations under gold/silver/bronze direction; JESIP adopts the same headings in its joint-doctrine briefing tool.

Practical point: the mnemonic is a memory aid, not the test. Decisions still turn on the live facts and the underlying law (College of Policing APP: Operations — Briefing and debriefing; JESIP Joint Doctrine — Briefing) — record your rationale, not just the letters.
