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). OCA is the preferred method of countering air and missile threats, since it attempts to defeat the enemy closer to its source and typically enjoys the initiative. OCA comprises attack operations, sweep, escort, and suppression/destruction of enemy air defense.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): OCA is the preferred method of defeating what kind of attacks?
Ah, so.. air and missile threats

The opinion of the majority of Croatian linguists[citation needed] is that there has never been a Serbo-Croatian language, but two different standard languages that overlapped sometime in the course of history. However, Croatian linguist Snjezana Kordic has been leading an academic discussion on that issue in the Croatian journal Knjizevna republika from 2001 to 2010. In the discussion, she shows that linguistic criteria such as mutual intelligibility, huge overlap in linguistic system, and the same dialectic basis of standard language provide evidence that Croatian, Serbian, Bosnian and Montenegrin are four national variants of the pluricentric Serbo-Croatian language. Igor Mandic states: "During the last ten years, it has been the longest, the most serious and most acrid discussion () in 21st-century Croatian culture". Inspired by that discussion, a monograph on language and nationalism has been published.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): According to Snjezana Kordic how long has the language discussion lasted?
Ah, so..
unanswerable
