Defensive Counter Air
From Baloogan Campaign Wiki
Defensive Counter Air
DCA operations protect friendly forces and vital interests from enemy air attacks; as such it is synonymous with Air Defence and Air Policing.
DCA consists of all active and passive air defence operations to detect, identify, intercept, and destroy or negate enemy air and missile forces attempting to attack or penetrate friendly battle space, or to nullify or reduce the effectiveness of such attacks should they escape destruction.
