I’m thinking McGonnagal could set up a decent nuclear defense system too. Charms that detect incoming airborne objects and transmogrify then into pigs seem right up her alley.
In general it seems that magic gives far more defensive options than technological weaponry. These days our defensive options are pretty much MORE ATTACK! But magic has invisibility, shields, teleport, (extra) secrecy and flipping time turners!
