Applying OCOKA in defence
Observation & Fields of Fire
- Position weapons to cover expected approaches with interlocking fire
- Use elevation and open terrain for long sightlines
- Assign sectors and clear kill zones of obstruction
Cover & Concealment
- Select terrain that offers protection and concealment
- Use fortifications and camouflage to reduce visibility
- Prepare alternate firing positions
Obstacles
- Use terrain, wire, or mines to channel enemy movement
- Cover obstacles with direct or indirect fire
- Avoid blocking friendly fields of fire
Key or Decisive Terrain
- Hold terrain that controls movement or offers advantage (e.g. high ground)
- Reinforce positions likely to be attacked
- Use terrain to protect flanks and enable movement
Avenues of Approach
- Identify all likely enemy routes
- Funnel the enemy into kill zones
- Maintain security on flanks and rear
