General Details
Name:  'Mech Mortar/4
Type (Category):  Weapon (Missile)
Technology:  Inner Sphere, Clan
Available To:  BattleMechs
Reference:  Tactical Operations (p. 324)

Description:
A rather old-fashioned concept, more akin to short-range artillery than a dedicated anti-vehicle weapon system, íMech-based mortars never really caught on through the centuries, especially thanks the existence of more effective missile launchers, and had largely vanished from Inner Sphere battlefields by the mid-29th century. Regardless, some agenciesónoting these weaponsí immunity from anti-missile fireóhave explored their potential as a suppression-fire alternative to LRMs, reviving the concept for modern times.

Game Rules:
Though their damage effects vary with the mortar types chosen, íMech Mortars otherwise operate in the same fashion as LRMs, and may be fired directly or indirectly per the standard game play rules. If fired indirectly, íMech Mortars follow all of the standard rules for LRM Indirect Fire, but do not require a completely blocked line of sight or a spotter to execute (though an additional +2 to-hit modifier applies if no spotter is present, reflecting the general lack of guidance systems on the mortar shells). If fired directly, a +3 to-hit modifier applies to the íMech Mortar attack because the shells still fly in an arcing trajectory towards the target.

íMech Mortars may only be fired by ground-based units. Airborne units may not fire íMech Mortars, nor may íMech Mortars be fired while submerged.

Anti-Missile Systems (including Standard and Laser types) may not engage incoming íMech Mortar flights.

Construction Rules:
May be mounted on any available unit type in accordance with the unitís 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 unitís 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 abilityís long range value if it is lower than the IF special ability value.
