-An OCA/Runway mission can be planned against an enemy airfield. Its purpose is to damage the runway to prevent the enemy from using the airbase to launch future missions. The flight will rendezvous with the rest of its package and proceed to its ingress point before lining up with and bombing the runway. If the runway is sufficiently damaged in a single turn it will be destroyed.
+An OCA/Runway mission can be planned against an enemy airfield. Its purpose is to damage the runway to prevent the enemy from using the airbase to launch future missions. The flight will rendezvous with the rest of its package and proceed to its ingress point before lining up with and bombing the runway. If the runway is sufficiently damaged in a single turn it will be destroyed. The amount of damage required to destroy a runway is defined by DCS.
 
 A destroyed runway will not be usable for missions and aircraft cannot be purchased or sold until the runway is repaired. Repairing the runway takes four turns and costs $100M. The AI will attempt to repair the runway whenever they can afford to do so. If the runway is damaged again before repair is complete the repair progress will stop and need to be purchased again.
