I had started a wimps empty wagon challenge (where I embark with 7 untrained dwarves, an empty wagon... and a battle axe). I had only gathered enough money for a single pick, so inside of a season my miner was legendary just from hollowing out basic storage and working areas. My only military dwarves at this time are my miner and a hunter who's up to expert marksdwarf.
For some reason, I received a goblin ambush about this time (don't ask how, I really don't know, I had only produced a few thousand db in goods total). My miner was drinking at the time, when a goblin maceman whacked him in the spleen doing light gray damage. So I'm thinking "oh crap, there goes my miner". I quickly draft my hunter to fight them off, but he's on the other side of the map stalking an elk or something, so he has to make a long run. In the meantime, I order the rest of my dwarves into the pitiful defensive tunnels I have.
All of a sudden, my miner just goes batshit crazy on the goblins. Without being drafted, he single handedly kills all 8 goblins with a copper mining pick. By the time he's finished, his light gray spleen wound has healed. One of the goblins limps away to be picked off by my hunter, but overall the entire ambush was run off by a civilian.
Later my hunter (turned professional soldier once I had my first immigrant wave) shot 6 goblins in the next ambush and bludgeoned one to death with a no quality wooden crossbow. These were bowgobs too, killed three caravan guards and four of my other marksdwarves. Yes, he had a pretty long title after that.
