A dedicated combat variant of their civilian Mister Handy, the Mister Gutsy series was developed by General Atomics International. It was commissioned by the United States Army shortly before the atomic apocalypse of 2077, with the first units seeing service in the liberation of Anchorage in January. The Mr. Gutsy is a personal protection automaton and comes equipped with heavier armor than most utility robots. It also carries a plasma weapon to be used in defense. The shell was rebuilt with lightweight armor plating, while the usual array of tools was upgraded with a plasma caster on a flexible mount. The key advantage of Mister Gutsies that separates it from other combat robots is its sheer maneuverability and spatial awareness. The Mister Gutsy is also upgraded with dedicated military software, including the ability to refuse orders issued by commanders who are incompetent or under court martial, remote link-up capability for updating orders in real time, and a brand-new Sergeant Major v.1.0 simulated personality that channeled the stereotypical Marine drill instructor and doubled as a vessel for state propaganda.
However, in its rush to present the Army with a working model, General Atomics cut corners and the resulting personality had issues stemming from vague definitions used in programming its neural network. The most notable of these was the fact that in the absence of orders, units defaulted to a patrol mode and attacked all unauthorized personnel with extreme violence, as per combat protocol Charlie Zulu 4. The military accepted these flaws, pressing them into service. They first bore MGZ-##### serials, before transitioning to the standard ABC-##### nomenclature. To distinguish between different variants of the robot, ranks were used: The baseline version was named Mister, with subsequent variants designated Sergeant, Lieutenant, Major and Colonel. A specialized field medic model was derived from the basic Mister Gutsy, with all combat functionality disabled and an encyclopedic knowledge of medical procedures, particularly surgery.
Mister Gutsy is one of the most dangerous robots in the wasteland, just behind assaultrons and sentry bots. Mister Gutsies are armed with either a plasma gun, roughly equivalent to a plasma pistol, 10mm submachine gun or a .44 pistol for long-range combat. At close-range, the robot relies on either a flamethrower or a buzzsaw, however higher "ranked" models sometimes have both. This affords the Mister Gutsy decent protection against both ranged and melee targets, a feature lacking in any other robot save the civilian Mister Handy. Additionally, due to their hover mechanism, Gutsy units do not set off the proximity fuses on mines.
The Enclave Gutsies are very similar to their free roaming wasteland counterparts, with the exception of its paint scheme. Instead of the normal matte olive green of the U.S. Army Gutsies, these feature a dark metallic color. Its optical sensors also differ from the standard yellow, instead being a deep red.

An unused Mister Gutsy creature with the editor ID 21ec0 is related to the Outcasts, however it just wears the regular green US Army skin. However, in the game files there is a connected skin for this Gutsy without a model.
End of information based on Fallout 3 cut content.
These unique Mister Gutsies can be found guarding the crashed vertibird in the southern Mojave, along with hardened sentry bots. Their HP exceeds a regular Mister Gutsy's by fifty points, and their general toughness is on par with the average sentry bot, accredited to their 10 Strength attribute (double that of the average Mister Gutsy).
Not much is known about the prototype series. This series was commissioned some time before the production series for trials, which were obviously successful as the production models were brought into service shortly before the Great War. They appear to have been salvaged by prospectors and reprogrammed for use by private individuals, such as the one located in a house in Nipton.

↑The Lone Wanderer: "I'd like to buy a robot." Tinker Joe: "Of course you would, of course! Well, it just happens that I've got a beaut of a deal on this customized Gutsy. And it's not just "Mister" Gutsy - he's a full fledged sergeant! "Sergeant RL-3" to be precise, the pride of General Atomics International. Comes complete with a simulated personality unit, so he's good protection and good company, too! And all yours for just 1000 caps." The Lone Wanderer: "Simulated personality? Sounds like trouble." Tinker Joe: "To tell the truth, it is a little trouble. But he can't help the way he got built.General Atomics programmed the Mister Gutsy to be a good soldier, but their definitions were a bit vague. So a lot of units had... issues. So we got a gung-ho, robotic soldier that's picky about the company he keeps. But he seems to like you, so it'll be fine." (FFER54NPC1.txt)
