How does a RSD work to reveal hidden units?
RSD P.88-89 says
"Remote Sensors can also reveal units (see Hidden Units, p. 168),
unless they are affected by hostile ECM systems, including Angel
ECM (AECM) and standard ECM (ECM), which will overwhelm their
abilities."
P.168 says nothing about RSD. Only PRB and LRPB (<-a typo in the rules? should be LPRB) specials are mentioned.
