General Details
Name:  Improved LRM 5
Type (Category):  Weapon (Missile)
Technology:  Clan
Available To:  BattleMechs (BM), IndustrialMechs (IM)
Reference:  Interstellar Operations (p. 96)

Description:
A marvel of miniaturization, the Clans reduced the weight of their LRM launchers by half and somewhat reduced their bulk. Further improvements would create the familiar Clan LRM, which even eliminated the weapon’s minimum range deficiencies.

Going a different direction, however, were the improved SRMs that appeared a full year before the new LRMs. Utilizing more powerful launch mechanisms, the early Clan weapons-makers increased the SRMs’ effective range by one-third, even though launchers themselves remained about the same weight and size as their original counterparts. Combining this advancement with the more accurate Streak targeting system would eventually consign the improved SRM to obscurity, but not before other manufacturing upgrades enabled the Clans to shrink their standard SRM launchers to half their original weight.

Game Rules:
Improved LRM launchers come in all the same rack sizes as their Inner Sphere equivalents, and maintain the same heat, ranges, per-missile damage, cluster tables, and volley-per-ton values as well. Improved SRM launchers, meanwhile, use the same heat, permissile damage, cluster hits tables, and magazine sizes as their Inner Sphere counterparts—but boast the range brackets of the modern Clan Streak SRM instead.

Construction Rules:
May be mounted on any available unit type in accordance with the unit’s standard construction rules.

Special Unit Abilities
The special unit abilities described here are intended for use with the Alpha Strike rule system:
 Indirect Fire (IF)
The Indirect Fire special ability allows a unit to attack a target without having a valid LOS to it via arcing missiles over the intervening obstacles, similar to how mortars and artillery work. This attack requires a friendly unit with a valid LOS to act as a spotter. The numerical rating for this ability indicates the amount of damage a successful indirect attack will deliver. Because they attack when other weapons cannot, damage from an indirect attack applies in place of the unit’s normal weapon attack.

Units with the IF and LRM specials may make use of all alternate munitions and Special Pilot Abilities available to the LRM special when making indirect fire attacks, but are limited to using the LRM special ability’s long range value if it is lower than the IF special ability value.

 Long-Range Missiles (LRM)
This unit mounts a significant number of long-range missile launchers and may fire them together as an alternative weapon attack instead of a standard weapon attack. This ability enables the unit to use alternate LRM ammo for modified effects.
