It would be better to have something like this.

Miner.
Even in the underground kingdoms of the dwarves, there is crime and lawlessness, and during difficult wars or internal conflicts, all members of the criminal underworld emerge, eager to get everything easily and quickly.
Those who fall into the hands of the authorities are sent to unbearably hard forced labor, where they spend days and nights mining and smelting ores for "nothing," and all the profits go to the state. Living in such harsh conditions for decades, miners can boast excellent physical fitness and a complete unwillingness to work anymore. During wartime, they have a chance to receive amnesty by joining the militia, which they take advantage of.
Miners are strong, hardened warriors, ready to break the resistance of anyone, even the most dangerous enemy – they are one of the strongest pillars of the dwarven army, but their weak weaponry prevents them from fighting on equal footing with other troops.

In principle, everything here is quite justified. And there is no need to overcomplicate things. As for the upgraded version, it could be that "the best miners receive normal weapons from the state and are released from work, etc." And regarding the lack of a counterattack – it is quite in the style of marginal dwarves to subtly stab someone in the side.
