Name:  LRM 20 (Prototype)
Type (Category):  Weapon (Missile)
Reference:  Interstellar Operations: Alternate Eras (p. 112)

Description:
Developed for reach, rather than punch, long-range missile racks are capable of indirect fire and a more concentrated dispersal of warheads. LRMs are typically mounted and launched in five-tube groups, with up to 20 tubes in a single rack, though Clan ProtoMechs may pack smaller sets. Standard LRM launchers are quite versatile, and can be easily upgraded with Artemis IV systems and even make use of a variety of special munitions. Inner Sphere launchers, which derive their impressive range from a ballistic launch angle, are notoriously less accurate close-in, especially when compared to their smaller and more compact Clan rivals. Nevertheless, their flexibility and solid reliability at long distances has kept LRM models like Delta Dart, Holly, Shigunga and Valiant in production for centuries.

Game Rules:
Missile launchers may not be fired if the unit is shut down or if its pilot/crew is otherwise prevented from acting, but loaded or partially loaded missile ammo bins are always live and will explode per standard rules if critically hit during game play.

Primitive prototype missile weapons (standard LRMs, SRMs, and their torpedo equivalents) apply a –2 modifier on the Cluster Hits Table for every successful attack, treating any modified result of 1 or less as a minimum result of 2.
