The Anvil was originally intended to act as a brawler BattleMech in its original design and testing phase. The 'Mech was paired with the Hammer 'Mech after the Anvil's tests showed the two 'Mechs would work well together. The Anvil is built using a Vlar 300 engine that provides the Anvil with both durability and a maximum speed of 86.4 km/h. The Anvils mobility is enhanced with three Chilton 365 jump jets that allow the 'Mech to jump up to ninety meters. The Anvil is armed with a short range arsenal that makes the 'Mech a powerful brawler when combined with its mobility, armor, and protection against advanced electronics with its Apple Churchill Guardian ECM Suite.[5]

Weapons and Equipment[edit]

The Anvil carries a powerful short range arsenal. The primary weapons are a pair of Sutel Precision Line Large Pulse Lasers which provide powerful medium to long range firepower. The short range firepower is bolstered with a pair of Martell medium lasers.[5]


  • possible variants 
    Numerous field or factory modifications have been suggested, not all of which have received designators. Downgrading the large pulse lasers to mediums and using the weight savings for armor and/or weapons is a common proposal.[1]
  • ANV-3R 
    A simple modification of the Anvil, the 3R model removes the three jump jets from the 'Mech and replaces them with three additional tons of armor, giving the 'Mech superb armor protection.[1] BV (1.0) = 1,264,[3] BV (2.0) = 1,496[6]
  • ANV-5M 
    Looking to increase the long range firepower of the Anvil, the 5M removes the Large Pulse Lasers and replaces them with two ER Large Lasers and two more medium lasers have been added to the 'Mech. BV (1.0) = 1,452,[3] BV (2.0) = 1,687[7]
  • ANV-5Q 
    The 5Q variant of the Anvil is a modification that looks to increase the 'Mechs heat dissipation abilities. The ECM Suite has been removed with a half ton of armor and the 'Mech has had two double heat sinks added to the design.[1] BV (1.0) = 1,210,[3] BV (2.0) = 1,336[8]
  • ANV-6M 
    The 6M variant of the Anvil is often paired with the 8M variant. This version is nearly identical to the base 3M model, but mounts a TAG system in the head in place of a medium laser. It also has slightly less armor on the torsos.[1] BV (2.0) = 1,366[9]
  • ANV-8M 
    The 8M variant is a radical modification of the 'Mech intended to provide artillery fire support. This is done by removing the 'Mech's entire arsenal, the jump jets, and reducing its engine to a 240-rated version allowing the 'Mech to move at 64.8 km/h. This version of the 'Mech also has a MASC system installed which allows it to travel at up to 86.4 km/h in short bursts. The 'Mech has had an Arrow IV artillery system installed as its primary weapon and an ER Large Laser for long-range combat. For close combat, the 'Mech has two ER medium lasers. Finally, the 'Mech is equipped with a Guardian ECM Suite to protect itself from enemy electronic warfare equipment.[1] BV (1.0) = 1,138,[3][10] BV (2.0) = 1,690[11]

Design Quirks[edit]

The Anvil has the following Design Quirks:[12]


  • In German products, the unit's proper name was translated to Amboss. The model code was accordingly changed to AMB-3M.
