While the wiki is your friend, I'll give you the just of what I do. First, I delete the default uniforms because of course I do. I delete everything from the leather armor one, and rename it to whatever i feel like. Usually ''infantry regalia.'' Then I add what I want them to wear. Mail shirt, breast plate, helm, gauntlet, high boots, greaves, shield, and battle axe. Then I set them to specific materials, usually dictated by what I can find on my map. [copper, iron, steel..] Then I make a second uniform like the first, but instead of an axe i give them crossbows. Then, when I get a dwarf that I want to be military, which usually means a badass name, I just [v]iew them, .. uh shit.. [p] i think, then assign them a military unit. People here will tell you that you should have multiple 2-man squads. I just have 1-2 squads of 10. My dwarves gain exp just fine. Once you get somje full suits to avoid the naked unhappy thought, which your uniforms to ''replace clothing'', otherwise they won't wear that steel helm because that echinda leather cap is just SO fashionable. Then once you have them armed and ready, just have them kill anything you want dead, and by the time the goblins show up, you can turn them into smoothies.
