The Laser Anti-Missile System, or LAMS, consists of one or more automated defense turrets that target and shoot down any enemy Missiles and Artillery that fall into its range. Utilizing a rapid-fire Pulse Laser, it is capable of destroying an LRM in a single shot, but multiple shots are needed to destroy the much larger and more powerful ArrowIV.
It should be noted that the visible laser beam from LAMS isn't where actual damage is delivered. LAMS has nearly 100% accuracy and instant aiming mechanics. It's unrelated to the effect the player can see. The reason for this is the difficulty in properly aligning the visual effects, due to engine limitations.
LAMS Base Turret
Bases are also protected by larger, stationary version of LAMS. These turrets feature much greater range than standard LAMS, and are also able to shoot down incoming and outgoing Long Tom shells, Thunderbolts, and bombs, unlike the standard mobile version of LAMS. These turrets shoot down both friendly and enemy missiles and artillery, resulting in sometimes severe damage to units attempting camping from base.
AMS was added to MWLL in version 0.2.0, though in 0.3.0 it was renamed to its canon designation, the LAMS. Version 0.3.0 also added the LAMS Base Turrets.
Typical BattleTech AMS utlize short-range, rapid-firing Machine Guns; however, what is currently implemented in MWLL is the Laser Anti-Missile System, which uses a compact Pulse Laser - when firing, it could develop relatively large amounts of waste heat, forcing equipped Mechs and Vehicles to manage it well or install additional Heat Sinks. The advantage of LAMS is that it does not require ammunition, making it capable of defending the equipped unit during long battles.
