official secrecy SHOULD protect either the aircraft's vulnerability to ground attack, [QUOTE]
Well the insurgents already know what weapon can bring down a C130, so it is clearly not a secret to them. So if the information is being withheld from the rest of us then it is a cover-up.
or the capabilities of ground to air weapons available to the insurgents
How is covering up that capability going to disadvantage the insurgents? They know what they have, they know that we know, so it makes no difference whatsoever if that information is more widely known.
