How can we confirm that the attackers have achieved success. How is success measured in this case. Was it completely successful, or they managed to achieve partial success.
One can only comment on this aspect if we exactly know what was their mission, what did they want to accomplish. Chaos, destruction of assets and killing of people, which assets did they want to destroy.
If they manage to damage a particular asset which was presumed to be their main target, the success they achieved has been partial.
The response has to be multi-tiered. We can not plan with surety that a perimeter would not or could not be breached. Therefore various response teams are earmarked and come into play at a certain time and space, depending on their distance from the incident site and the type of response needed.
The system needs to function, irrespective of the commander becoming a casualty, because of his own fault or a long range weapon hitting the place in the rear where he is located. The system replaces the commander, ensures the type of response needed, when to send in additional forces in case the initial response fails or has been partially successful etc etc.
We can only comment on what we may know. In the absence of complete information, appropriate conclusions cannot be reached.
It is never easy to analyse the environment for want of more information and clarity of such information.
nothing even on papers
