Traction benches are made at the mechanic's workshop. I'm not sure why. Perhaps it's because they have moving parts.
Thanks, I was wondering where those things were.
You're welcome and thank you. I kept trying to draft/activate my dwarves and didn't see how to do that.
Other things I have noticed related to military:
Be very careful digging underground. it seems that the game has a lot of underground diversity and even though I embarked in a grassland area, I quickly found lots of things that wanted to kill me from below: trogs and even GCS. The normal route of building a central staircase and then exploratory mining is now quite suicidal if you run into a GCS unexpectedly. Even more interestingly, you might accidentially dig into the side of an underground lake and spell instant flooding "fun" for your fort.
Moral of the story, Dig carefully.
When underground, traps become key in case something from the deep wants in from below. You're not just defending against gobbos anymore. It is VERY true that you could face a GCS in the first month of spring embark if you are not careful (in a grassland biome!).
I have two works for you: "hatch covers." Again, narrow chokepoints with traps have saved me from three waves of trog invasions before the GCSs (yes plural!) decided to walk over their dead bodies/jammed traps and eat me.... Hatch... covers.
Herbalism, your friend:
There are no more underground rivers, or even pools. I'm not even sure how magma works anymore, because there don't seem to be pipes that I've seen (i could be wrong, you can use finder to get one, but you can't view it at embark screen)
HFS is also revamped so only Toady knows that one.
However, there are a crapload of things underground in large caverns with underground lakes. This means that you will likely encounter a lot of plants on any soil layer floor and moreover, those underground caverns, all seem to have muddy stone. Yeah... that means that they have pregrown trees and shrubs.
