The Dragon was the product of the Tactical Ground Support Vehicle Program, a component of the UNSC's reconstruction initiative. As the threat of the Covenant and its merciless directed energy weaponry had largely been subdued, the UNSC Defense Force made public its interest in developing more heavily armored, multirole vehicles.
Throughout its service career, a number of Dragon variants were developed. These ranged from mainline technical upgrades to what some consider to be "far-fetched" experimental platforms. Nonetheless, very few of these modified vehicles failed to prove themselves in the fields of modernized combat.
Dragon infantry mobility vehicle — The original, basic model. It mounts a variety of armaments and is capable of transporting as many as six passengers, in addition to a driver and gunner.
M184 "Wyvern" armored personnel carrier — A Dragon with an noticeably modified body; it is capable of carrying up to twelve passengers. It mounts a standard weapons package.
M1095 infantry fighting vehicle — An up-armored model that made use of two twenty millimeter N/AG-34 autocannons. It repeated proved its efficiency against better-armed insurgency groups.
