The Ha Otoko is primarily a defensive, second-line BattleMech. Clan Diamond Shark first fielded the cheap 'Mech when they helped Clan Nova Cat evacuate from Clan space in 3060. Clan Jade Falcon merchants were the first to point out that the Ha Otoko seems meant to be sold to the Inner Sphere, being easily modified to accommodate similar Inner Sphere weaponry, in addition to the Oriental styling of the 'Mech's exterior. The Ha Otoko is protected by thirteen tons of armor.[5]

Weapons and Equipment[edit]

A missile boat, the Ha Otoko uses a pair of torso-mounted Type XX "Great Bow" LRM-20s and a pair of arm-mounted Type X "Short Bow" LRM-10 launchers. However, it only incorporates thirteen single heat sinks, so MechWarriors must carefully manage their heat. Many only fire the LRM-10s when enemies attempt to flank them.[5]


  • Ha Otoko 2 
    This Clan tech variant of the 'Mech appeared during the Jihad in 3074[2], which makes the 'Mech a general purpose role. The 'Mech has been fitted with some the newest technology of the time period. Based on the Clan version of the design, all the original missile launchers are removed, except for a single arm mounted LRM 10. The launcher retains only 1 ton of ammunition in left arm with the weapon. Complimenting the LRM launcher in right arm, the 'Mech has been given a Class 30 Hyper Assault Gauss Rifle with 4 tons of ammunition. The 'Mech been given a Plasma Cannon and four ER Medium Lasers round up the 'Mech weaponry in closer range fighting. To accommodate these new changes, the 'mech engine has switched to a XL Fusion Engine and its armor protection has been slightly reduced. BV (2.0) = 2,348[9]
  • Ha Otoko 3 
    This variant introduced 3082[2] replaced the chassis of the HKO-1C with an Endo Steel version and removing the arm mounted missile launchers, engineers added extended range Large and medium lasers and Artemis IV FCS to the remaining missile launchers. An ECM suite is also added to interfere with Word of Blake electronics, and AP Gauss Rifles counter enemy infantry units.[10] BV (2.0) = 2,206[11]
  • Ha Otoko-HR 
    Introduced in 3077, analysts believe that this variant is Clan Diamond Shark's attempt to use Inner Sphere equipment for themselves rather than an attempt to generate business. Powered by a Light Fusion Engine, the Ha Otoko-HR has the survivability of a Clan Extralight Engine without racking up the significant cost. The HR refit also uses Inner Sphere produced heat sinks, and a Small Cockpit to provide enough room for the weapons loaded. The HR mounts a pair of LRM-20s but also includes a Mech Mortar/8 in each arm. These weapons may not be as effective as missile launchers, but their immunity to Anti-Missile Systems could explain their presence. BV (2.0) = 1,547[12]
