Filius: Is this closer to what you're after?
That's 8 units assigned. Fielding the troops themselves does not take labour (equipping them will), so you don't need to spend a labour point on that. You don't know where the Yetis are yet (or in fact of the existence of any of the other players), but you can send the raiders out to explore and take advantage of any targets they find. If you attach the explorer to them, they'll cover more ground looking for targets. If you attach the general to them, they'll have a better attack bonus if they find any targets.
Either way, you have 2 labour spare. You can assign them to tiles to work or possibly try building an improvement with some of that stone you're mining out. Up to you.
Also, as a general point: Should units drafted on a turn be allowed to be deployed on the same turn? Or should it wait 'til the turn after? In AoR you had to wait for weapon production, but I'm currently allowing people to field untrained armies quickly.
Edit for clarification:
Nobody knows of the existence of the other players just yet. The black is just filler, but as of Turn One it is also the extent of your map. Exploration will help fill in that detail, but you won't get actual maps until someone researched Mapmaking.
I'm currently tweaking the exploration/raiding mechanics. In a raid, 100 conscripts
will walk over 10k citizens (but if there have been no units drafted that turn by the defending town, they will automatically generate conscripts of their own) for the purposes of
raiding. Raiders don't stick around, they just get in, nick stuff, and get out again. Conquest is probably going to require a whole different mechanic.
As a rule of thumb, though, I will probably set raiders to loot up to 3 goods from a town (per raiding unit). I haven't scripted maximum looting capacity into units yet, though. Right now, if units are carrying any goods when they lose a battle in the field, the loot drops to the battlefield and can be picked up by the victors (or anyone going there to salvage). I may add a 'looting' stat if there's interest in greater or lesser looting power.
