The Sanity Check was implemented in september of last year:

Thats good news, i didn't know.
however, it is in my opinion that such militia guard should already be in place before an enemy or monstrosities come in.
Its quite logical that any region without government/authority has an established way of protecting its self non or the less, against bandits and rogues as well as small armies from realms.
No sane peasant would allow monsters through its gates, welcome them and then get killed or eaten by them, time after time again.
Especially in good populated towns land who are not starving should be able to stop most rogue from even entering the town, killing the rogues even before they do damage.
Someone in that tread also suggested different equipment or even troop types per region, perhaps that's a little to much work, instead every peasant militia could randomly have a ranged attack, some militias would be more effective at ranged attacks then others.
Someone mentioned slingshots, i am quite sure they where used in this period, but bows and even simple spears where not uncommon among the commoners either.
Even the poorest peasant would have some nasty sharp tools which they know how to handle very well.
A scythe or a hand plow of some kind could be well used against cavalry, bows and stones against infantry and any knife, axe or even hammers against archers(if they can get that close).
Most archers of realms during our time frame where in fact Peasants, who where raised with using a bow at home for small hunting.
In other words, most peasants could shoot as good or at least nearly as good as a soldier, but perhaps they wouldn't have no fancy leather armour(if they even had any, i dont think so), or perhaps as much arrows as a unit commanded by nobles would have.
