"The Mighty Hood goes down" scenario is also reprised in OP. (And perhaps EAW) Also, OP contains the Pleaides Turkey shoot and the "Wrath of Khan" scenarios.
While Tulwar got the Nimble Ships info, he neglected the "small target" info. (Small targets getting free ecm, wow, thought that was an SFC3 innovation!)
E1.7 Small Target Firing Modifications
All shuttles EXCEPT standard size fighters: range 12-24 = +2 ECM, 25+ = +4 ECM
Fighters + drones: 10-19 = +2 ECM, 20+ = +4 ECM
Nimble ship: 15-29 = +2 ECM, 30+ = +4 ECM
This is for EFFECTIVE range, which takes into account lack of lock on due to sensor damage, cloaking, natural ECM, etc.
PF's and interceptors are considered "Nimble ships" for this rule.
These ECM points are not cumulative with EM, the owning player may choose which to use.
They are cumulative with specific weapons penalites when fired at drones.
They are cumulative with EW.
Seeking weapons fired at small targets are unaffected by this rule.
Hope that helps.
HAND!
