No, it couldnt be via xml, normally in civ, you cant kill a land/naval unit with a plane, so when you do it, it doesnt trigger the txt_key_xxxx because it doesnt recognize it, so editing the txt_key_xxxx wont matter, neither will it effect when you attack it with a plain because 85% of the time you just damage it,
so i thought python would possibly work? a simple program that works like this: if unit is land or naval, and if unit is killed by a land unit, print message unit X was killed by (country) unit Y
Normally Air units cannot destroy land/naval units because of this tag
<iAirCombatLimit>50</iAirCombatLimit>
If you set it to 100, it will be able to destroy land/sea units just like any others. Then the message will be displayed accordingly
