: I understand that we've gotten descriptions of the Soldiers in the universe
: section on Waypoint. They're automatons created specifically for the war
: against ancient humans, mostly used for boarding action and navigating the
: smaller hallways aboard human ships/interfacing with human
: systems/operating human vehicles and technology. However, they have a lot
: of similarities to the Promethean Knights, who we know to be composed
: Forerunners and humans. Are the Soldiers also supposed to be composed
: individuals, or are they simply highly-intuitive Forerunner AIs?

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.
