It’s always the same thing. Russia bad, Middle-East bad, China bad. USA saves the world.
I like playing Ace Combat because the nations and geopolitics are made-up so it doesn’t feel like you are sitting down and watching U.S. military propaganda for 10 straight hours.
At least in the first game, the Marines are mostly inspired by Aliens though. Coincidentally it's also the only game in the series which began development before 9/11.
The Marines of 2 and 3 still retained their scifi action figureness, in Reach the human soldiers just look like DOD concepts for the American military in 15 years
