Have anyone see this happening?

I've never seen before, though I will try.

Chasing after enemy cavalry in the shooting range of own arhcers, might work.
Or in melee combat, which enemy did not have archers and javelinmen participated and ours got involved might also good.
If there appeared golden arrow, above units head, it means friendly fire.

Though it's hard to get picture of the moment friendly fire take place.

I have not seen a single instance of FF casualties, even when my own troops were thoroughly mixed with the opposing ones. I kind of miss the occasional "oops, sorry!" in the earlier games.

The yellow arrow means one of the enemy was killed. Damage to your troops is shown in red.

I'm not 100% but I don't think there's friendly fire.

Honvedseg you miss it? It was absolutely hideous in CoW.

Absolutely hideous, and probably authentic. I edited the squads.txt file to reduce the ammo loads slightly in CoW to something more realistic. That reduced the FF hits after contact by a large amount, and made skirmishers a bit less devastating in the early game. I couldn't picture skirmishers running around with a huge bundle of 8 or 10 javelins anyway, 3 to 5 seemed like more than enough baggage. I also reduced the skirmish archers by either 2 or 4 arrows, for similar reasoning.

IIRC there is no friendly fire in Arena. Realistic it may be, but it's too painful a gameplay mechanic
