So they fight people, specifically people iwth lots of tech on hand. Because EM-seeking is useless against Grimm, and most vehicles. It works by searching for, and homing in on, electromagnietic radiation. Usually this guidance system is used to target radar platforms, since most other targets don't put out enough radiation to warrant this kind of guidance system. They're mostly used for softening up a target's AA capabilities, since radar is kind of important for that.
