OAKOC — Terrain and Situation Analysis
Learn to read what any piece of ground actually allows and denies — the terrain foundation MDCOA and ACH both depend on.
Every threat assessment rests on an assumption about what the terrain makes possible. Most people never check that assumption. This seven-lesson course teaches OAKOC — Observation and fields of fire, Avenues of approach, Key terrain, Obstacles, and Cover and concealment — the five-category terrain analysis framework this platform’s MDCOA (INT-06) and ACH (INT-01) courses both depend on for real, grounded input.
Foundational, not optional
OAKOC doesn’t tell you what a threat will do. It tells you what the ground allows — and every downstream judgment is only as good as the terrain picture underneath it.
Lessons 01–07
01
Terrain Analysis as an Intelligence Discipline
The container/framework/method distinction, and why terrain isn’t just rural ground.
02
Observation and Fields of Fire
What can be seen, from where, and how far — including vantage points you don’t control.
03
Avenues of Approach
Every route in, not just the one everyone uses — and what each implies about warning time.
04
Key Terrain
Ground worth controlling, defined by consequence — not size or prominence.
05
Obstacles
Existing and created obstacles, and how channeling a route creates new key terrain.
06
Cover and Concealment
The distinction most often conflated — and the false-confidence error that results.
07
Capstone: Building a Full OAKOC Assessment
Synthesize all five categories into one written terrain analysis for a real site.
