AECM Blocks ->
* Artemis IV Bonus LOS Only (improved accuracy),
* Artemis V Bonus LOS Only (improved accuracy and + increased cluster/amount of to hit),
* Beagle Active Probe bonuses (detect/classify targets at increased range, detecting shut down Mechs) <-BAP is the actual component that alerts a pilot of being jammed if ECM is nearby, that little "low signal" symbol or something like it should only be for BAP
* Bloodhound Active Probe Bonuses (Same bonuses as BAP + can negate bonuses of other equipment such as Stealth Armor, Void Signature Systems, NULL Signature, and ECM - Original game rules state AECM nullifies Bloodhound bonuses, new rules simply still all "ECM Suites" are negated against Bloodhound)
* C3 Master Computer bonuses (Target Data Sharing IE What kind of Mech, Whats on it, "Range To Target" Sharing Benefits and "free" TAG ability) <-Note Range To Target benefits means whichever C3 in the lance is closest to the target, all others in an unbroken C3 chain get the same Range to Target benefits as the closest Mech, which opens up interesting things like firing your weapon outside normal range and still doing damage
* C3 Slave bonuses (All Master computer bonuses if "in-network", also does not have "free" TAG ability)
* SSRM bonus (improved accuracy/liklihood to hit)
* NARC Beacon bonuses (a beacon emits a homing signal, the true way in which SRM/LRM's can home in on a target provided the SRM/LRM fired is loaded with the more expensive "SRM-Narc Capable" or "LRM-Narc Capable" ammunition, it also allows actual indirect fire, whereby the Missile simply seeks out the target without aiming, unless you're in a C3 lance to "see" the target <- ECMs simply shut off the beacons homing signal)
ECM/AECM do NOT block -> Any missile system from locking, except SSRM against AECM, both ECM Suites however slightly reduce chance of more missiles hitting (but not all) or negates accuracy bonuses as described above.
Bonus notes: SSRMs can still dumb-fire as they are supposed to, but for some reason was always absent in MWO, a dumb-fired SSRM behaves exactly like an SRM (chance of wasting missiles to hit).
Also TAG - mainly only for guiding "semi guided LRMs (3057)" or designating an Arrow IV artillery missile, Artillery from Land or Naval, note a Naval unit actually gains a bonus -2 to likelihood to hit (Arrow IV, Actual Artillery units or Naval not in game)
Either way the way PGI did it is bonkers backwards going on now 2-3+ years ago. Nothing but a total rewrite of ecm, lrm targeting behavior, all that equipment, etc. would work though, as just changing a few things here and there piecemeal would probably cause more trouble. Its a lot more in-depth in BT, like a massive game of paper-rock-scissors.
