Your story is interesting and definitely has potential. I just want to offer some constructive criticism. Most of chapter one is in present tense, but the paragraph starting with "Landon’s RAV pulled its assault rifle..." is written in past tense. I’d also like more description of the RAVs and how it feels/sounds/smells like to be inside one.  I’m looking forward to the next chapter!

Since you like mechas, I’d recommend Sleeping Giants by Sylvain Neuvel, a really awesome read. 

I’d really appreciate it if you could follow and leave a comment on my novel page. https://www.inkshares.com/books/kzar-i-jupiters
