Am not 'shocked' in the least. Local authorities will always be the quickest responders. The problem here is that the institutional delays I mentioned works both ways. The local authority will report a military force of unknown origins is conducting some operations within his sight. At the higher level, someone, for good or bad, is too incredulous of that news, after all, no one above his pay grade told him of any military exercises, so is it possible that this could have been one of those 'surprise' job intended to weed out some incompetents? Confirmations must be available. At higher still, someone demands more confirmations from other people who may have overlapping authority to do 'something'...And so on...and on.
The trespass of a country's territorial sovereignty is not something that occurs daily and when it does, it is usually accidental and can be resolved at the lowest diplomatic levels. But if we are talking about armed men in various aircrafts, that is a different story and it will demand everyone to confirm his suspicion to his satisfaction. The confusion works up and down the chain of commands and this institutional problem have been exploited in past military operations, so good that it is quite popular for movie plot devices as well.
