Medium Range Missiles Are Broken; Fix Them
MRMs are not broken in the sense that they're too good. I know they're designed to work with C3 systems and that they have the new Apollo system to help them suck less.
The first step is changing their weights and heats.
Name Heat Damage Short Medium Long Tons Crits Shots/Ton MFM 10 4 1/Missile 1-3 4-8 9-15 3.0 2 24 MFM 20 6 1/Missile 1-3 4-8 9-15 6.0 3 12 MFM 30 10 1/Missile 1-3 4-8 9-15 9.0 5 8 MFM 40 12 1/Missile 1-3 4-8 9-15 12.0 6 6
Second, I'm taking the same route that they took with old school autocannons: Specialty Munitions.
Penetration warheads feature a shaped-charge designed for far deeper penetration into armor than standard MRM warheads. Larger than MRMs, each ton of Penetration Warhead ammo only carries half as many rounds.
When Penetration Warheads hit a target, roll to determine the first location hit and note how many total missiles hit.
Roll a critical hit on the first location hit and add a modifier from the table below according to how many missiles hit. If less than five missiles hit, do not make a critical hit roll.
Dmg Total Roll Bonus Rough Amount of Damage
1-5 No roll
6-10 -4 More than half of an MRM 10
11-15 -3 More than half of an MRM 20
16-20 -2 More than half of an MRM 30
21+ -1 More than half of an MRM 40
Scatter Warheads fragment in-flight to release submunitions that engulf a unit completely. They are larger than normal MRM munitions and the shots per ton of Scatter Warhead ammunition is half that of standard MRM ammunition.
When an MRM firing Scatter Warheads hits a target, roll on the Cluster Hits Table as normal, then roll on the Cluster Hits Table again for the result of the first roll. For each point of damage that results, deal it to the target, rolling for hit location for each point of damage.
Note: On a '32' result on the MRM 40, roll on the 30 and 2 tables of the Cluster Hits Table and add the result.
For example: Bobby fires an MRM 30 at an enemy 'mech. He hits, and rolls on the '30' Column of the Cluster Hits Table. He rolls a '9', which returns a result of 24. 24 of his missiles are going to hit, bursting to release their high-speed submunitions. He rolls on the 24 column of the Cluster Hits Table to see how many of those do damage. He rolls a '5', and 16 of those hit. He rolls for the hit location of each of the 16 separately.
As per LRM/SRM specialty munition of the same name (Total Warfare, page 141).
Medium Range Saturation rounds spread out over a wide area to fill an area with unguided missiles. Saturation Missiles have additional fuel and 'random-jets' that make them larger than regular MRMs. A ton of Saturation Missiles only yields half of the missiles as a ton of standard munitions.
An MRM firing Saturation Missiles does not suffer the +1 to-hit modifier of MRMs. In addition, subtract one from the to-hit penalty that is a result of the terrain a unit is in. Because so many missiles are lost to cover this area, Saturation Munitions that hit a target roll on the Cluster Hits Table for a rack half their size.
Rough guidance systems have been jury-rigged onto standard Medium Range Missiles, increasing their size and allowing them to follow the signal of friendly Target Acquisition Gear. Partial Guidance Munitions are twice the size as standard munitions and at ton of ammo only has half as many shots as a standard ton.
Partial Guidance Munitions ignore the +1 to-hit penalty of MRMs when firing at a unit designated by a friendly TAG. The additional fuel for the on-board guidance system doubles the damage from the explosion of a ton of Partial Guidance System ammunition.
MRMs can carry minefield munitions analogous to those of LRMs. The minefield size is equal to half of the MRM's rating.
