The Lineholder was the first BattleMech design to come from Kressly Warworks, and is designed around a set of "Common Sense Rules" for 'Mech design. This approach has produced a 'Mech with a good ground speed and respectable amount of armor and firepower. Thanks to its mix of off-the-shelf weapons and equipment the Lineholder is a reliable 'Mech that is easy to repair and is dependable in battle. However, the ultimate selling point for the Lineholder, especially to its target audience of small units and minor nobles, is value and price. In the first year of sales, the Lineholder was historically successful compared with other 55-ton BattleMechs, and quickly became the garrison machine of choice for minor factions able to afford brand new BattleMechs.[1][5]

Weapons and Equipment[edit]

Designed as an affordable medium 'Mech, the Lineholder is built with an array of conventional technologies. Using a standard Kressly GRF1A-MDX chassis to carry a Core Tek 275 engine, the Lineholder is able to reach a top speed of 86.4 km/h, allowing it to keep up with all but the fastest light and medium 'Mechs. The Lineholder also carries 10 tons of Kressly Stoneskin 30M standard armor protection and mounts 14 heat sinks.

The primary weapons on the Lineholder are a pair of LongFire V LRM-5 launchers which allow the Lineholder to keep an enemy at long range and enable the 'Mech to provide limited indirect fire support. These are backed up by a BlazeFire Systems large laser and four Intek medium lasers to protect itself in close combat.[1]


  • KW1-LH8 "Linebreaker" 
    A recent upgrade of the Lineholder, this variant of the 'Mech carries a pair of RAC/2s in place of the two LRM-5 launchers and the four medium lasers, and an ER large laser in place of the large laser. Nicknamed the "Linebreaker," this variant was designed for the Federated Suns. Following the commencement of the Jihad, however, production ceased. BV (1.0) = 1,081,[9][10] BV (2.0) = 1,330[11]

Design Quirks[edit]

The Lineholder is subject to the following Design Quirk:[14]


  • In German products, the unit's proper name was altered to No-Pasaran, which is a Spanish expression well known in Germany, which translates to They shall not pass. The model code was accordingly changed to KW1-NP2.
