I found out that group of drafted miners can make half decent fighters.
Legendary miners armed with only their pick make excellent warriors, I found out recently.
My situation: my fortress was progressing nicely, and I had a moat plus a drawbridge protecting my entrance, and two wardgogs by the bridge to warn me of any sneakers coming across. It is the only entrance, so thieves would need to get across there.
However, I hadn't realized that dogs won't give a warning until enemies are upon them. In this case, a six-gob ambush party, already across the bridge and atop my dogs. My three archers were either sleeping, eating or drinking, and all my wrestlers were sparring in barracks. I activate all the squads and prepare for battle. There's a human caravan inside the fort and the gobs would need to pass that before getting to my civvies, so I am not too concerned.
A expected the goblins make short work of my wardogs, but they don't enter the fort, instead they climb uphill past the gate, to get to f5-6 dwarves incoming with wood hauling jobs. The soldiers won't make it in time to save them.
All is not lost! A legendary miner is close by, destroying natural ramps off hillsides. I draft him and set him on the gobbos from their rear. First to feel his wrath is the goblin archer, well behind its comrades. It goes down very quickly, possibly a hit to some vital spot, and the miner turns his vengeful pick against the other gobs, rescuing a dwarf that is down and out and tormented by a lashmaster.
In the end, the miner kills all six gobs in very short order, not getting a single scratch despite wearing nothing but some x(cloth stuff)x. The soldiers arrive at last, their job just being to count the number of goblin corpses. Losses on my side: zero dead, one gravely injured hauler (he survives his wounds eventually).
I am thinking of retiring his copper pick and placing it into the temple of Armok, next to the artifact idol. Too bad I can't name the tool.
