Interesting comment considering the vast majority of F16 and for all intents and purposes, ALL F15E sorties are CAS...
And how do you come to that conclusion?
Deep strike is completely different than CAS.
A/A is completely different than CAS.
CAS is unique. Basically, CAS means the application of firepower under positive control in proximity to friendly forces.
Want CAS delivered the way it should be? Set the Wayback Machine to watch A-4 Scooters delivery the goods way done low. They never missed!
