I'm Shocked, Shocked I tell you that the DOD paid for that and the NFL took the money. The NFL that paragon of American virtue, and values. Excuse me , I have to sign off to kill my fighting dogs, pregnant girlfriends, punch my wife in the mouth, and perform a drive by shooting. But hey we took care of the under inflated footballs.
Care to quantify "a lot"? I don't think it's all that much, but that could be because I don't respect them as people. Great SEALS while they were active duty, but self glorifying after the fact... Their books are full of "I'm so awesome!" it's disgusting.
I've seen it used in both -16s and -10s...with a gateway, it works very well with Link 16 for air to air SA. A/G it is terrific but many times the gnd units are dislocated from the radio set so they still must be tracked via other means.
As for CAS, you'll hear engineers say digital CAS is great via VMF and other means. Most pilots think it sucks. Ok for getting mission info on the way there but once in the AO, I prefer radio comms and old school Com flow.
