Well, this guy isn't military, but I still consider him to be badass.
One of my founders, by the nickname of Stonehand, was to be an artist. Every day, when he wasn't mining, he was smoothing out that which he had dug. Eventually, he became a legendary miner, then a legendary engraver. All well and good. Then, one day, there was a goblin ambush across the moat. Stonehand was out for some reason I can't recall, and got shot at least five times before the champions could get out to take care of the goblin ambush. This is why a wall now encompasses all of Shorebolder the Great Black Tower-Castle of Light. In any case, Stonehand was gravely wounded, but, being superdwarvenly tough, he recovered in under a year. However, amongst the massive amounts of wounds he received, Stonehand had both his eyes shot out (without any damage to his brain, though).
So, poor Stonehand is blind, but he continues doing his work. It's only now that he begins to actually engrave images; up to this point, he had only smoothed walls and floors. Eventually, he picks up masonry as well. His true crowning moment of awesome came when it was time to dam the river. All the others had abandoned their posts, drinking, seeping and whatnot, but there were still three wall tiles to be completed. Stonehand, however, braved the river, building wall after wall, though he was interrupted time and time again. Three times, he nearly drowned in the raging waters, but he continued on. The water splashed about him as he screamed to the heavens, placing stone upon stone, until finally, he had done it. The river had been tamed, and Stonehand stood upon dry ground.
Later on, I discovered that he had reached legendary in another skill: furnace operating. I had turned it on long ago, when we didn't have any true smiths, and had forgotten to turn it off. Since they were magma furnaces, I decided that my quadruple-legendary blind dwarf deserved a new profession name. He is now Stonehand, Elemental Master, as he has tamed earth, water, fire, and metal. He has been given the finest tomb in the fort, engraved by himself, so that generations to come will know that the true measure of a dwarf is not just how many goblins they kill, but rather the strength and courage they show in overcoming all the challenges that the world throws at them. And even without sight, he know that his images are beautiful.
