Terrain Considerations - O.C.O.K.A.
The following military aspects of terrain are as outlined in Army Field Manual 7-8, Infantry Rifle Platoon and Squad (p.2-8).
|Observation and Fields of Fire||The potential offered to observe enemy approach and the fields of fire offered in terms of the range and other characteristics of weapons available.|
|Cover and Concealment||The potential for providing cover from both direct and indirect fire and concealment from enemy observation.|
|Obstacles||In the attack, the effect of restrictive terrain on the maneuverability of the unit. On the defense, the availability of natural or man-made obstacles to disrupt, turn, fix, or block an enemy force and protect friendly forces from enemy assault.|
|Key Terrain||Terrain whose seizure or retention affords a marked advantage to either combatant. Hills, plateaus, or other terrain features which could provide an advantage to the element occupying that position would be considered key terrain.|
|Avenues of Approach||On the offense, avenues of approach afford greatest protection and places attackers at enemy vulnerable spots. In the defense, expected routes of enemy approach to a position, to be covered by fires from defenders.|
