ELectronic INTelligence ideas are taken from B5 Wars. They extend the rules for sensors, stealth and targetting, and also add in some stuff for command and control.

All ELINT modifiers affect the range to a target - either adding to it (making the target harder to hit) or subtracting from it (making it easier to hit). No modifiers can do better than halve the range to the target. Likewise, no modifiers can do more than double the range to a target.

There are some exceptions to this rule. Any modifier which multiplies a range rather adds/subtracts from it, is applied after all other modifiers have been applied, and may do more than halve/double the range.


Sensors may be used to effectively shorten the distance to a target. Each sensor module can lock onto a single target each round. The target is declared when movement orders are written.

A standard sensor suite increases the effective range band of weapons by 1/6th. E.g., a pulse torpedo (range bands of 6”) will now have a range band of 7”. Beam weapons will have their bands increased from 12” to 14”.

An advanced sensor suite increases the band by 1/3rd. E.g., pulse torpedos now have a range band of 8” and beam weapons 16”.

If multiple sensor suites are used against the same target, then only the best applies. The extra sensors have no effect.
