nuke range, tactical nuke like in civ3

[McBierle]

hi guys,

i made a new unit (nuclearsubmarine) capacle of transporting 2 'specialunits' TACNUKES i made in the CIV4SpecialUnitInfos.xml file. I wanted those to be like the smaller nukes as there were in civ3.
The problem is i didn't find a way to reduce the range of a nuke. That would also be interesting for those cruise missiles as there were in civ3.
Has anybody a clue how to limit the missiles range? And don't say "<iNukeRange>" that just defines the are of effect of the nukes (as far as i know).

thanks cu mcbierle
