Personally I think that the laser dotting should allow missiles to hit regardless of ECM considering it's a visual tracking.
Except neither of the "laser-guided" missile systems (Artemis IV and TAG) are "
beam riders".
"In an effort to enhance the accuracy and lethality of standard missile racks, the first Star League developed the Artemis IV fire-control system. Mounted in a dome near the enhanced launcher, the Artemis was in essence an infrared laser designator, target lock mechanism and tight beam microwave transmitter that - together with specialized missile control systems - helped to focus the spread of all missile volleys so enhanced." (
TechManual, pg. 206)
"More than a simple infrared laser-based target designation system, the TAG system tied into the user’s on-board targeting and tracking systems and used its own integral tight-beam laser communications array to link into the receptive guidance systems of certain friendly artillery warheads and guided bombs." (
TechManual, pg. 238)
Both Artemis and TAG include the laser designator within themselves, and use an additional transmitter (radio-based for the Artemis, and laser-based for the TAG) to send the targeting information from the launching 'Mech to the missiles in flight.
In the case of TAG with an independent spotter: the targeting information is sent from the TAG unit to the TAG-carrier's targeting system, which is then sent from the TAG-carrier's targeting system to the missile-carrier's targeting system, which is then sent from the missile-carrier's targeting system to the missiles in flight via a laser using a technique known as "
free-space optical communication".
Artemis works the same way, but is more self-contained (no independent spotter) and uses
microwave (that is, radio) transmissions to transfer targeting data from the missile-carrying 'Mech to the missiles in flight.
Neither system uses optical sensors to directly detect and home in on the reflected laser beam, in the manner of the "beam-riding" system that most people think of when they hear the term "laser-guided".

An ECM system - like Guardian - would generate
electronic noise on a wide variety of frequencies... with specific exceptions made for those specific frequencies used by the carrying 'Mech's own sensor systems and communication channels (as well as those of its allies).
Furthermore, BattleTech's basic gameplay rules (having it affect Artemis, Beagle, Narc, and C3, but NOT affecting TAG) and its more advanced gameplay rules (in which it does not affect IR, MagScan, or Seismic sensors) would seem to imply that (in spite of certain fluff statements) Guardian (and the later Angel ECM) are purely radio-based jamming systems (that is, they would not incorporate, among other things,
laser jammers or
IRCM systems.)
So, TAG should be immune to the effects of Guardian not because of the "visual tracking" that
it is NOT using, but because it does not operate using the radio-based systems that Guardian was designed to defeat.
