Maybe it shows how little time I had to spend with the opendev, but: is there an option to retreat in between strategic turns of a battle? That is, after the three (or so) rounds have finished and the global layer has advanced one turn.

If not, I think there should be, at least at a cost. It seems quite historical to have to fight every battle to the last man, once committed. Things happen. The enemy gets unexpected reinforcement or does unexpectedly well during a battle. It would be good to have the chance to re-assess whether that battle still makes sense or your 1:1.5 odds have slimmed to 1:3 odds. To prevent this from dragging things out too much, maybe there should be a cost, in addition to the upfront retreat, say -30 health to all units left.

(if something like this already exist, please apologise and feel free to ignore.)
