Miners in the military - yes or no?
No weapon is more dwarven than the pick, and no skill more dwarven than mining. It also levels up very, very quickly, especially when digging soil. Therefore, miners seem obvious candidates for a military squad. When exploring a cavern, it is good if miners can defend themselves from the endless onslaught of giant bats and giant cave spiders. However, there are also some problems:
Miners, if assigned picks as weapons, will not use said picks for mining.
Drafted miners are "recruits", causing "complained about the draft lately", which if repeated can lead to !!fun!!. (This seems to be the biggest problem.)
Miners training will not mine, making digging work slower.
Mining does not train discipline, so they must also spar and slay captives.
In my previous fort, I used a marksdwarf squad as both ranged support and the fortress guard (using wooden crossbows so beatings were non-lethal while still being extremely dangerous to forgotten beasts, kobolds and others), kept hunters, miners and woodcutters separate, and had a dedicated squad of close combat warriors who did nothing else. Generally new migrants with combat skills, including hunters, were left civilian if female and drafted if male.
Is is worth drafting miners, especially in an early fort? If it is, how should it be done to avoid repeated complaining about the draft or mining work being too slow? I thought of training my miners as low level wrestlers, but feared that this would cause them to wrestle instead of striking with the pick.
