Hi everyone, I think this mod doing the mentioned thing: https://www.nexusmods.com/fallout4/mods/28645?tab=description Quote from the mod's description: "Emergency assembly points: non-guard settlers will run to the nearest point when the settlement is under attack. Guards, robots, and companions, instead, will fight against the hostiles as default. Useful to increase the chance to keep alive the settlers set in mortal mode. - Optional: a non-guard settler, owning a “Reservist Dog Tag” in the inventory, will join the fight instead of looking for an assembly point. - Optional: a guard settler or a robot, owning a “Rearguard Dog Tag” in the inventory, will remain in the rears instead of joining the fight."
