Imagine such people making use of such weapons while riding on wyverns, like using lances that shoot lightning bolts or fireballs at attack choppers while the wvyvern joins in the attack.

Was giving some thought about how much of a challenge would a modern military would have if there are warrior-mages or magic weapon users riding on wyverns.
