Spartans look a little small?

I’m judging it based off of their environements compared to them also how vehicles look. If the Spartans are 7-8 ft supersoldiers, then these marines better be dwarves in these maps by comparison, or, the more likely outcome, that Spartans need to be a little bit taller? Again, I haven’t seen marines in comparison but i’m just using environments here to compare, so they could easily come out and show marines being really small. Imho I think Spartans should be just a little bigger.

7-8ft are Spartan 2’s only. 6ft and up are 3’s and 4’s. They’re more normal sized.
