So, I pretty much know how to use military, but it's damn annoying. I had a squad of five Axe Lords(Danger Room FTW) and another one with semi-skilled ones. When a human siege arrived I thought this would be their acid test. Preparing some more cage traps, I lowered the bridges and the humans started to move. Well, in a few seconds most of the human army was a bloody mess. There I was proud of my military, designating the humans' stuff for melting. One of my Axe Lords decided to chill away by the brook, when an ambush came composed of one human crossbowman. The crossbowman killed the Axe Lord in one shot and another quite skilled military dwarf.
So, yeah, it seems ranged weapons are actually extremely effective, even against steel-clad killing machines. Then the horrible thought came to me: "What if I get a siege composed of only marksmen?" So, now I'm here thinking on what the hell to do. Of course, I should put together a marksdwarf squad, but even now I have trouble finding useless enough dwarves to put in my squads. So, how to manage the military, so that I can train a sufficient number of skilled soldiers, whilst having them doing their old jobs, as well? Migrants would be good, because there are lots of useless dwarves in migration waves(my second squad is all migrant), but migration waves are too damn rare. I even want to explore the caverns, because I have a cavern like 7 levels underground and I desperately want to find magma, because charcoal->coke from bituminous coal just doesn't seem to work out.
