How many Chieftains in ODST

I can’t find the answer to my question anywhere. I don’t have the game and I don’t have the time to watch through hours of Halo 3: ODST gameplay YouTube videos. Can anyone tell me how many Chieftains there are, War Chieftains and regular? 6? 7? 10?

i cant tell you off the top of my head. may i ask why you want to know?

Don’t know the exact number but I’m pretty sure one appears during the mission when you blow up the ONI building, then again in the cinematic on the rooftop level, and I know there are at least 2 on the last level when you’re holding out for the phantom to arrive.

It all depends on what difficulty you do it on too, but if I had to guess I would say 4 to 5
