If there is a save mechanic inside of combat it will end like every not-ironman xcom game. It ends in uncounted reloads until every strike you do hits and your guys don´t get hurt. This is neither intended nor should it ever be possible in my opinion.
Though the save on exit seems like a very good idea and would deal with the no-time-issue.
"I am a Paladin!"
>OMG, Malthus, there are no damn paladins in Battle Brothers...<
"OK, OK! Then I´m a wrecked down minstrel drunkard pretending to be a paladin, singing so wrong in the midst of battle that even the undead run in fear... Better?!"
