"Clashes" is a must read, its all about USAF, USN and VPAF tactics, weapons deployment/development, Electronic Warfare etc.
Very interesting and it has many accounts of air combats all through the text, it doesnt get boring to read.
Another Vietnam related book which is not on yourlist is "scream of Eagles" by Wilcox ... its about how the USN realized that they must use better tactics with the big smokey F-4 to beat the small MiG ... its the story of how Top Gun came to life and how the lessons worked in the skies over Vietnam... a very interesting read!
I have all the Thud related books of your list, and can say that all are very good.. many interesting stories.
Of all, I like "When Thunder Rolled" best, because its written by a (back then)junior officer , which has a very interesting view on Thud flying over the north.
"Palace Cobra" is the sequel in which he returns for another tour in 1972, Flying the F-4 this time. Also a very interesting read...
