How often were soldiers killed by their side's arrows?

I was playing Total War, and it occured to me that when archers were firing into the skirmishes, only the enemy side ever got hit, despite the men being scattered around, and closely packed.

So, how often did archers hit their own men?

how would medieval fighters/warriors/military recognize friend from foe?
