The first OmniMech both designed and built by the Lyran Alliance. The OmniMech is named after the rank held by officers in the LAAF. The inspiration for the Hauptmann is drawn from the Daishi OmniMech used by the Clans. Using information from captured Daishis and data gleaned from the construction of the Firestarter OmniMech, which was shared by the Draconis Combine, the end result is a powerful OmniMech capable of defending itself in most combat situations. The Hauptmann is built on a standard chassis and powered by a 285 fusion engine, adding to the 'Mech's durability as it cannot be killed by a side torso loss. The Hauptmann has eleven double heat sinks fixed on the chassis and can add more if needed in its various configurations. For protection, the Hauptmann carries eighteen and a half tons of armor and has CASE fixed in the right torso to protect against an ammunition explosion.

Weapons and Equipment[edit]

The primary configuration carries a varied and powerful arsenal. For long range combat, the Hauptmann carries two ER Large Lasers as its primary long range weapons. These give the Hauptmann Prime a good long range damage capability. For close combat, the 'Mech has an LB-X Autocannon/20 for devastating close range firepower backed up by two Medium Pulse Lasers, an ER Small Laser, and a pair of Streak SRM-2 launchers. Finally, to protect the 'Mech against enemy electronic warfare systems, the Hauptmann Prime has a Guardian ECM Suite.

Alternate Configurations[edit]

  • Alternate Configuration A 
    Intended for close combat, the Hauptmann A is armed with four ER Medium Lasers as its primary short-ranged weapons with a pair of SRM-6 launchers linked to an Artemis IV fire control system for increased missile accuracy. For increased mobility, the Hauptmann A has three jump jets that allow the 'Mech to jump up to ninety meters. Finally, to defend itself if it ends up in a long-range firefight, the Alpha configuration mounts a Gauss rifle. To handle the massive heat load, it carries an additional six double heat sinks.[1] BV (1.0) = 2,172[3][6], BV (2.0) = 2,311[1][7]
  • Alternate Configuration B 
    Configured for both long- and short-range engagements, the B configuration of the Hauptmann has a pair of ER PPCs which give it the capability to engage an enemy at long ranges. For close combat, the 'Mech has three Medium Pulse Lasers and a devastatingly powerful Ultra Autocannon/20. To handle the high heat generated from its weapons, the B configuration has five additional double heat sinks.[1] BV (1.0) = 1,662[3][8], BV (2.0) = 2,208[1][9]
  • Alternate Configuration C 
    The C configuration of the Hauptmann is intended to close with its enemies and wear them down as it approaches, delivering the killing blow at short range. For long range combat, the Hauptmann C carries an LRM-20 launcher linked to an Artemis IV fire control system to increase the accuracy of its missiles. For close combat, the Hauptmann C has a massive Heavy Gauss Rifle. This is supported by two ER Medium Lasers, an ER Small Laser, and a Medium Pulse Laser. This configuration of the Hauptmann has an additional two double heat sinks and a Guardian ECM Suite to protect itself from enemy electronic warfare systems. BV (1.0) = 2,122[3], BV (2.0) = 2,322[10]
  • Alternate Configuration E 
    The E Configuration was, like the D configuration, developed during the Jihad. It was designed to use a large quantity of range-weaponry as its primary focus. The Hauptmann's right arm is fitted with a Gauss rifle with 2 tons of ammunition mounted in that section. In the left arm, a plasma rifle has been fitted. Both arms have their lower arm actuators removed to allow for the pilot to flip arms. The plasma rifle's 2 tons of ammunition are stored in the left arm and in the left torso. The 'Mech's only secondary weapons are a pair of 5-Tubed Multi-Missile Launchers mounted in each side torso. The Hauptmann has been given 3 tons of CASE protected ammunition for the missile weaponry. BV (2.0) = 2,298[12]
  • Alternate Configuration M 
    The Hauptmann-M configuration is equipped with a Clan-spec ER PPC. This is supplemented by three LRM-15 launchers. This long-range weaponry is a good choice as the M configuration carries a C3 boosted master computer into combat. BV (2.0) = 2,214[14]
  • Alternate Configuration T 
    This configuration carries a Clan-spec Ultra AC/20 in each side torso. Each AC has three tons of ammunition. Each arm carries a single TSEMP Cannon. The left torso is protected by CASE II, while the right torso is protected by CASE. BV (2.0) = 3,031[15]
