Mad Dog Hardpoints


The MDD-B dedicates one side to short/medium range and the other side to long range. The right side has three Medium Pulse Lasers in the arm and two Streak SRM 6s in the side torso. The left side has an LRM 20 and two ER Large Lasers.

As an OmniMech, it can use OmniPods from other Mad Dog variants for additional hardpoint variations.


  • The first missile hardpoint in each side torso allows up to 20 tubes. The second supports up to 10 tubes.


  • No AMS
