Would be nice, if you look at the HQ units the Battalion HQ in particular he has those bars that show personnel strength, morale, condition, suppression and all those that change throughout the fight. So all the data is probably there including casualties so some type of Situation Report that you can toggle whenever you want could include all this info in raw numbers, average ammo, morale and so on amongst the Battalion.
For platoons or squads that have no contact the SitRep can show "Cut Off - No Contact" or whatever all the information is there and can be obtained and analyzed but some type of overall battle condition report would be mighty cool.
