Argh thats what I thought...these bums are draining my treasury. I plan to ship them off to a particularly dangerous province. Mwahahaha!

Yes the milita event has been previously discussed on the forums and the vast majority agree it's a bad event.
What's really bad is when they land in a province where there's also another army and the end result can be starvation/disease.

The milita can land in deep secure provinces as well where killing them might take 8+ turns of marching. The milita event means you pay more gold upkeep, you need to feed more units and you have a ton of low morale weak units.
