The Dragon Fire is like the Marauder 9S . . . it has some EW capabilities but it is not a E-War mech, its a shooter- notice the BFGs.
For E-War, IMO, shooting is a tertiary, maybe secondary if you are including iNARC & ARADs, concern. Sort of like the discussion of a command mech/vehicle not really having many weapons- the job is to command, or in this case wage electronic war.
Part of the problem in defining is the rule differences- TW has ECM unable to be toggled over to ECCM let alone Ghost Targets which is like IRL giving false targets. EWar gets more important with the more wargame/simulation rules you use from TacOps- double blind, hidden units, hidden record sheets, LOS diagramming, and more advanced LOS/sensor rules can magnify the impact.
