What does OCOKA stand for and how does it inform terrain analysis in METT-TC?

• A. Observations and fields of fire, Cover and concealment, Obstacles, Key terrain, Avenues of approach; used to identify terrain advantages and threats.
• B. Operational Control Of Known Areas; used for basing
• C. Observations Of Critical Obstacles and Key Areas; used for evasive maneuvers
• D. Organizational Chart Of Known Assets; used for logistics planning

Answer: (A)

OCOKA is a terrain-analysis framework used to identify how the ground will affect a mission by focusing on observations and fields of fire, cover and concealment, obstacles, key terrain, and avenues of approach. Observations and fields of fire help determine where you can observe and engage the enemy from safe positions, shaping where you place units and how you provide security. Cover and concealment assess what can protect you from fire or keep you hidden, guiding choices about exposure, camouflage, and movement. Obstacles flag natural or man-made barriers that could slow or block routes, informing breaching plans, route selection, and engineer tasks. Key terrain points to features that, if controlled, give a combat advantage or disrupt enemy movement, guiding where to concentrate effort and how to occupy terrain that yields an edge. Avenues of approach analyze potential enemy routes of attack or movement, enabling you to deny, disrupt, or leverage those routes through disposition, obstacles, or fires.

In METT-TC, terrain analysis through OCOKA translates the battlefield’s physical landscape into actionable decisions about where to position, maneuver, and secure forces. It helps you identify favorable lines of sight and fields of fire, choose defensible positions, anticipate bottlenecks and choke points, and plan routes and security measures that exploit terrain advantages while mitigating threats.
