How does that work, exactly? I noticed that my dwarves would stray from the burrow they were told to defend, is there a way to keep them there without locking them there? Would a station order be more effective? I have two areas, an ambush point for melee and a line of fortifications for marksdwarves.
I do what Lazarus does, I believe. 1x1 burrow in 4 spots. One in each corner of fortress, behind a smoothed-fortified wall. All four 1x1 are just ONE burrow however. Not 4 seperate burrows. I name it 'Roost' for sniping roost, then I schedule 8 of 10 marksdwarfs to defend 'Roost' burrow every month, every year, giving 2 of 10 soldiers, leave.
What happens then, when toggled active, is they go to whichever 1x1 is closest, sometimes 3 here, 2 there, 1 here, 2 there. By the time I have 24 marksdwarfs, or four full squads visiting the 4 1x1s, they all get covered decently, sometimes 6 soldiers ea, sometimes 8 here, 3 there, etc... Most of the time, they are inactive, and doing Civie chores.
Only takes one to observe a nasty, nearbye. Then the plinking starts! I go one step further and assign a metal ammo stockpile, copper bolts usually, in reach of the 1x1 burrows. This keeps them firing long into the night. I don't pick up spent bolts, to avoid casualties. By late game the 5x5 region border is covered in spent bolts.
When a lull occurs I pick some up to melt down. Some fun can also be had, by turning off the marksmens food and water supplies, and overlapping that Roost burrow with your Danger burrow. Your nurses will bring drinks up to them. Never had any starve on me, but I suppose they could. Reason, for removing their supplies is so they hold more ammo.
Not sure if that works, but its sound logic. I like sound logic. Knutor
