Built on the same chassis as the Sentry and Watchman BattleMechs, the Cuirass is designed for the cavalry role. Its higher ground speed allows it to quickly strike at an enemy formation's flanks and withdraw. Though slower than lighter cavalry units, the 180 meter jump range offsets this disadvantage. To make room for the weapons and engine, the Cuirass uses an XL gyro, XL engine, and endo steel construction. CASE protected the autocannon ammunition, but pilots should remember that the eight tons of armor is not enough to stop heavy weapons fire. The use of the extralight engine and gyro also make the 'Mech vulnerable to penetrating armor shots. Another drawback is the use of single heat sinks on the 'Mech, and although this reduces cost, MechWarriors who are careless with their heat management can quickly find themselves shut down.[1]

Weapons and Equipment[edit]

The Cuirass' main armament is the RAC/5 carried in the left arm. Identical to the weapon used on the Legionnaire and Blade BattleMechs, this weapon can easily knock smaller opponents right off their feet. Three tons of CASE-protected ammunition keeps the Cuirass fighting for a long time. Unlike the Legionnaire, the Cuirass can close with an enemy unit and finish it off with either its ER medium laser or, if it needs to cool down, the two ton sword mounted in the right arm.[1]


Design Quirks[edit]

The Cuirass is subject to the following Design Quirk:[7]
