When I ran the "militia" response to the Ice Giant Elemental attack I didn't lose any available infantry. Not sure if "militia" was supposed to disclude the local military or not. I knew it wasn't a good response to pick, but I wanted to try every available answer while play testing. I didn't really suffer for it except that Kalle only received 5 xp. Seems to me that the rampage should have beaten down a few infantry and maybe tapped some of my gold after it destroyed a few buildings. Also - I'm thinking the response should vary based on how much infantry is currently available. If all your infantry have been used previously, maybe that response shouldn't be an option - or better yet - you end up sending your troops in tired and they get slaughtered. :0 Just an out-loud thought...
