In response to some of the comments, and because I myself find it annoying at times, I've made a new mod, "Mighty Militia" to deal with these so-called "volunteers". It changes "militia" to "fanatic", raises morale from 8 to 10, and makes them holy, so they can be blessed, and consume less resources. In the interest of game balance, you'll be required to build a temple if you wish to recruit any, and their original armor, hit points, etc all stay the same. If it needs to be tweaked, let me know. This changes all 4 militia units (that includes C'tis lizard militia). I e-mailed it to Kris, but for now you can grab it here:
