I've been told that Probes and ECM have no effect when mounted on Aerospace units (Convenional and not). And I don't want to be a pest but if they don't have any effect why does the Torrent Heavy Bomber mount an ECM Suite and why is it considered to be better protection than the 3 tons of Hubris Heavy Armor the Torrent carries?
Then there's the following Double Blind Rule on page 222 in Tactical Operations.
Airborne Units: Sensor ranges for airborne units do not change, though LOS exists to all units on the playing area. If using a High-Altitude Map, an airborne unit must be in the Ground Hex Row to make a sensor detection roll. If using a Low-Altitude Map, an airborne unit cannot be at Altitude 10; it must be at Altitudes 1 –9 to make a sensor detection roll. In both instances, the airborne unit is considered to be in Hex 0909 of the ground mapsheet corresponding to the hex occupied by the unit.
If I read it right, Sensors and Probes can be used against ground targets but only at certain altitudes and only from hex 0909. If that's correct does ECM also protect Aircraft from ground units under the same circumstances? I know the aircraft would still be visible, unless hidden behind clouds or mountains, but would the ECM make targeting the aircraft more difficult?
Conversly, if an aircraft is low enough to use it's sensors against ground units can those same ground units use thier sensors and probes to detect aircraft even if hidden by clouds or mountains? Unless of course the aircraft's ECM protects against those sensors?
What about against other aircraft? Can Probes detect aircraft at greater ranges in an atmosphere, the way they can in space? Or if they're hidden behind clouds or mountains?
