I have to ask; is english your second language? Your grammar is very good, which is impressive since I've noticed that that's the part that most ESL people trip up on. It's just that here and there you forget to put a word in that should be there, make improper use of capitalization, or accidentally use a different word than you should.

For example; in the part right after they disable the AA guns, Reaper says:

“ Just about enough for them to get if they were on, you see me? ”

"Just about enough for them to get me if they were on, you see me?" would be the proper way of phrasing this sentence.

Another example would be around the part where they are trying to escape and are being shot at with rocket launchers.

Just then a Rocket flies by them almost hitting the Warbird as well, Ethan looks back to see the Innies which Launchers.

It should be "innies with launchers". The words "rockets" "innies", and "launchers" shouldn't be capitalized either.

I have to stress, your story is pretty good. It's keeping me engaged despite these little mistakes here and there, but there are going to be plenty of people that wont be as forgiving and would rather stop reading because of them. I just wanted to give you a little help and nudge you in the right direction. If you need more help, try asking around for someone to help proofread your story. That should iron out most of the mistakes you might make.

“I am Faust…I have seen your actions, your history, and your sacrifices…I am here for a second chance at life.”

My browsing history? Better not...

Also: I've said it before and I'll say it again. The largest turnoff is when a story is written in present-tense. Just... ARGH.

“Infiltrate, collect intel, and blow the facility.”

should of added more detail

Ethan jumps off the Warbird and starts firing at the Innies with everything he’s got, he then shoots at the Tangos holding the Launchers and ends them quickly, he then takes a bullet to his left shoulder.
