At 1 ton, the C-LRM 5 is the smallest of the Clan Long Range Missile family. Its indirect fire allows support 'Mechs to pummel the enemy from a safe distance. The C-LRM 5 is capable of light damage at range but the small number of missiles fired means ammunition shortages are not a problem. An LRM's minimum range is 180m, below which the damage decreases to nearly nothing at point blank range. The C-LRM 5 is also subject to Heat Scaling.
While ECM makes the effective use of LRMs more difficult, it is possible. If you are alone with an ECM equipped foe, staying within 181 and 200m will allow you to use your weapons with lock. If you have a TAG spotter, as long as they are at least 181m from the target and maintain the tag on the target, you will have your target lock. If you have a PPC spotter, you have your target as long as they keep the ECM disabled.
Clan LRMs have several differences from their Inner Sphere counterparts.
They fire in a stream rather than launching all tubes simultaneously.
Clan LRMs will still do damage even if the target is within the 180 meter minimum range. However, damage decreases as the target gets nearer.
Clan LRMs do more damage per missile and generate more heat.
