Is there any way to put them out, or is there nothing I can do but wait for it to eventually go out? In my game I've had one of my guys on fire for like 4 turns now. He and another guy both got lit on fire at the same time, and the other guy stopped being on fire the next turn.

At first glance I recalled being able to do this with a medkit, but I spent some time searching and cant find anything that corroborates that.
