Well I must admit the idea of fighting a dragon is already an awe inspiring prospect (as dragons are a representation of nature's wrath) especially considering such creatures already existing physical abilities (which even in a very young dragon would still be more than capable to besting most armies). Fighting a dragon wearing armor. I am hard pressed to imagine a more desperate struggle nor a more glorious battle. If one loses than one will still be remembered for being brave enough or stupid enough (or very possibly both) to challenge such a creature. If one wins than one will have achieved a feat exceeded in difficulty only by either defeating or becoming a deity in a single lifetime.
