Let's face it, everybody loves Danaerys Targaryen's dragons. And why not? They bring the rain… well, more like they bring the kind of fire and brimstone that'd make Col. Kilgore from "Apocalypse Now" smile in the morning.
There are planes that are very loved as well… like the A-10 Thunderbolt II. This plane is best known for its GAU-8 "Avenger" cannon, which brings a load of firepower. But the dragons have more payload than the beloved "Warthog." In fact, they can devastate an entire area. Just look at this clip from "The Spoils of War."
And like the BUFF, Drogon unleashes long, long trails of fire, like the string of 51 Mk 82 500-pound bombs (or M117 750-pound bombs) that a B-52 delivers in those carpet-bombing raids. Who remembers the dragons tearing apart the slavers' fleet? Did you know that B-52s have been equipped to carry AGM-84 Harpoon anti-ship missiles?
But Drogon was doing a fair bit of that in a close-air support role. That is the bread-and butter mission of the A-10 Thunderbolt. His first pass cut a hole through the Lannister lines. And like the A-10, which is legendary for taking damage and getting back home, Drogon showed he could take a hit and still remain very dangerous. Hell, he even pulled the same "fire from the ground" maneuver Doug Masters did, and Jamie Lannister is darn lucky he isn't a crispy critter after that "gun run."
This does seem perplexing. Are Drogon, Viserion, and Rhaegal more like BUFFs, or are they more like the Warthogs that our ground troops love? There are good arguments both ways.
In this case, the best answer may be that they combine the best of both of these legendary planes. They can handle the close-air support mission, but they are also very dangerous against strategic targets. The Mother of Dragons would have beaten Cersei a long time ago if she'd used `em properly at the beginning, instead of making big-time blunders.
