: See, this part was really confusing to me too. Waypoint says the Soldiers are
: AIs but they actually display more personality than the Knights. They
: taunt you, talk to each other, and go "urrrghh" when they're
: killed. Why program behaviors like that into purely AI drones? The
: taunting I could kind of buy as a psychological tactic, but why would the
: Soldiers need to vocalize to relay information to each other? Why would
: they scream when they die?

: You could say the Forerunners just liked to do that kind of thing with their
: war bots, but then you have Sentinels and Enforcers that do none of that.

Now that right there is the true question, maybe to make humans feel more empathetic to their foes and therefore hopefully cause them to hesitate in key moments, but thats a really long stretch and if so why not make them look like people or whatever to increase that.
