Highlight own troops, enemy & allies !!

I find this very useful on larger battles where it just gives me a great idea of how my troops are holding up. Especially in infantry heavy fights, where you are usually trying maintain the line in order to flank with cavalry/archers etc.

And yes, I missed this one for a while too =)
