Status Bar Meaning for Units?

[Thales]

For each unit there are two status bars. The top one shows the units health.. What does the bottom one display?

I noticed that the "healers" could restore a unit, going from red back to green (top status bar). However, I did not notice any change on the bottom status bar.

this is experience.

your citizen soldiers will gain experience by fighting, and a tiny bit by hunting. You can gain experience by garrisoning in barracks/stable. When the bar is filled, your unit will promote to the next rank with better fighting ability.

melee units get health, armor, and damage with each rank, ranged units get more health and accuracy with each rank.

Interesting. Thanks.
