There are only about 10 areas to mouse around, and each gives you the exact staus of the units there, I'm not sure how you would put that info for all the units in each area (especially the small ones). Where there are unresolved battles you will see the "double roundel" as in Western France. Hovering the mouse over that will reveal teh contents, and give you an estimate of attacker and defender losses and the chance of causing the enemy to retreat.
In this case teh PAnzerKorps have red arrows, indicating they used extended movement (more than one area - using extra supply) and the tac bomber used regular movement (they can fly to their range - 2 areas in this case for their 1 supply) none of the french units have been attacked yet. IF they had been attacked in a previous battel in teh area (you can attack in a big stack, or a series of attacks - it can be useful against small stacks to send a "probing froce" in first to get then engaged, (lowering their evasion rating by 1) and then hitting them with teh main body of your attack. IF you out number the enemy this is a crucial tactic to maximize "kills" by increasing your hit chance. For example if you attack with 5 dice, agaisnt a Panzer Korps with evasion 8 (they have durability 3) you only have a 6% chane to get a hit, but if you lower its evasion to 7 by an air or probing attack, your chance of hitting goes up to just over 22% - nearly 4 times higher. IF you can attack it out of supply goes down another 1 and goes up to just over 50%. So you can increase your hit chance by nearly 10 times if you plan your attacks right.
You can see a second set of unit "boxes" above the battle - if you click on one of those the movement path the unit used to get there will appear, in this case becasue the PanzerKorps revealed teh Allied fleets off teh coast, it is not "undoable" as the red Xs indicate. and teh usually red double "undo arrow" at teh bottom of the movement bar would not be greyed out. You can either click on individual arrows to undo to teh previous area, or use the undo whoel move button.
