The toolbar displays the active regiment and the regiment's selected target. Near these unit pictures you see any medals won by either of the units. These medals measure the regiment's experience.
On the battlefield you see an area of small pips showing the radius of potential movement of the active unit. If a pip is green, it means that no enemy can fire into that space presently and that the active unit can move their without any fear of immediate damage. A red pip means that enemy units can fire into that space.
Each regiment's display on the battlefield includes a green damage bar. The size of this bar tells you roughly how many of the regiment's troops are able to fire. As the regiment is fired upon the size of the bar decreases as more men are taken out of action. If the bar ever disappears it means the unit is totally destroyed.
It is likely that the morale of the regiment will break before total destruction occurs. When the green bar turns yellow, the regiment can only run or surrender.
