As I recall, (and this may pertain only to the USNR) the fleet-air reserve readiness through the post-Korean war years suffered horribly, especially in materiel readiness, until about 1970 when a complete reorganization was underway to rectify the inability of the reserve units to augment the fleet forces. Don't know if this had a parallel in the ANG but the use of antiquated (WW2) equipment suggests a similar situation.
After Vietnam when the USN reserves were flying roughly comparable hardware the reserve performance often tended to surpass that of the regulars.
