UNSC is surprisingly primitive for being 500 years in the future. No shields for ground forces, case ammunition, no hovering vehicles etc.
SPARTANS however could probably beat an N7 operative. Hyper-reflexes being one of the reasons.
Shields are really getting up there in technology and it makes sense we wouldn't have them yet. Well, Spartans have them.
You sure? Shepard did kill some Reapers, he wiped out the Collectors, he either was the saving grace or sole condemner of
three sentient races, survived a direct lazer blast, died and came back, etc. Spartans? They killed some 2 feet methane-breathing aliens... oohhh, impressive..
