I want to know the answer to the following question:
OCA is the preferred method of defeating what kind of attacks?
All the background I'm provided with is that "Offensive Counterair (OCA) is defined as "offensive operations to destroy, disrupt, or neutralize enemy aircraft, missiles, launch platforms, and their supporting structures and systems both before and after launch, but as close to their source as possible" (JP 1-02).". Is that enough to answer the question?
