Hello, everyone! In wording of cybermine said that, they triggered only on hackable targets, but in the section about template and suffering hits says "Troopers who suffer a successful Cybermine impact will have to perform two Saving Rolls against Damage 15. If the target fails either Saving Roll, it will enter Immobilized-B State." So basically if fireteam with hacker in it walk(in one line) in to cybermine trigger area, cybermine detonate and all fireteam members (even if they non-hackable) suffer 2 saves (because template of cybermine hits them all, they all suffer hits from template) and go to Immobilized-B State ?
Yes, RAW it is like that: a hackable model is required to initiate the detonation (following all the stuff in the general mines), then all the models affected by the template can do the Reset-3 roll if they declared it, and those who fail need to pass two BTS 15, or get IMM-B. I think this is the only instance in which a non-hackable troop can suffer such state, which I agree is kinda silly... but Cybermines were introduced in the end days of N3 with the same wording, so I assume they are working as intended, as strange as it looks like.
