This mech paper model is Hatchetman, a very distinctive BattleMech because, as its name suggests, it carries a 'Mech-sized Hatchet, from the video game MechWarrior 4, the papercraft is created by BLaaR. The size of finished model is about 229 (H) x 113 (W) x 130 (D) mm.
As well as being the first design to carry one, the Hatchetman itself was the first totally new 'Mech produced in the Inner Sphere in over a century, and was also the first production 'Mech to use a Full-Head Ejection System. Despite being first manufactured in the Lyran Commonwealth the Hatchetman was actually designed by the enigmatic Dr. B. Banzai of Team Banzai, a mercenary unit associated with the Federated Suns' New Avalon Institute of Science. Thus the 'Mech was also a signal of the growing cooperation between these newly-allied Successor States.
At its heart the Hatchetman is an urban combat 'Mech. Once it has safely escorted friendly forces out of a city the 'Mech assumes the role of guerrilla fighter, ambushing from hiding places to blast an enemy apart at point-blank ranges with its impressive weaponry or cleave them in two with its hatchet. This was illustrated in the design's first combat test, when elements of the 4th Proserpina Hussars raided Sevren and were literally cut to pieces by a mostly Hatchetman-equipped battalion of the 26th Lyran Guards which lured the enemy into an industrial park. Where the Hatchetman is at a disadvantage is on open terrain, as its relatively slow speed, light armoring and general frailty leaves it vulnerable to other 'Mechs.
Initially the Hatchetman's first production run was limited to garrisoning large Lyran cities, but its early successes inspired further deployments and the 'Mech soon began appearing in the arsenal of the Federated Suns, particularly among the Crucis Lancers and 1st Kathil Uhlans. In the wake of the Fourth Succession War and the formal creation of the Federated Commonwealth, the Hatchetman was selected to become one of the standard designs for the Armed Forces of the Federated Commonwealth. Demand for the 'Mech soon began to outstrip Defiance Industries' ability to supply it, even after tripling output from their Hesperus II factory, and so it contracted Johnston Industries to set up a Hatchetman line on Johnston. The recovery of lost Star League technology eventually allowed for the creation of the HCT-5S in 3049, with additional variants created in years hence.
Among the other realms the Draconis Combine managed to capture a few examples of the Hatchetman and successfully copy most of the design to produce their own following the War of 3039, however the 'Mech proved to be unpopular and the program was canceled. Hoping to salvage the project Independence Weaponry experimented with the design and eventually created a variant more palatable to Kuritan pilots. Out in the Periphery the introduction of the Hatchetman caused quite a stir within the Taurian Concordat when a group of mercenaries brought along their old HCT-3Fs upon integrating with the Taurian Defense Forces. Protector of the Realm Thomas Calderon ordered Taurus Territorial Industries to reverse-engineer the design, which they finally succeeded in accomplishing after much delay by 3054, only for production to be halted in 3066 when the Fighting Urukhai destroyed TTI.
