The militia is a form of Vyseni rebels who live in the "Shelled School". Apparently after the man who asks for help to get the humitarian aid drop, a few days later the militia will come your door and will ask you if there is suspicions regarding your neighbor poking around the aid and taking items from it are correct and if you say no some of your charachters may brighten up thier mood and if you say yes then your characters may also become sad but there is a reward if you say yes but if you say yes they will terminate that man who asked you for help.
