HBS 2+2, Wharton, and MIT Sloan Deferral Chance Me

Looking for some criticism on my application thus far for senior year applications.

About myself:

• Ivy (Not HYP, one of the ones with small grad school representation)
• ~700 GMAT (from practice tests, will study until I take it closer to senior year)
• Going into the military as an officer upon graduation w/ ROTC
• low income, immigrant, and first gen (I only mention this as Harvard gives low income under the second bullet point on their website for who they prefer)
• 3.8 GPA Poly Sci and English concentrator
• Internship at a law firm, this summer I am doing one at a 3 letter intelligence agency with Army ROTC
• Very good letters of rec from professors, I will ask the lawyer I interned for to give me one too

Does my application have a chance, assuming I keep my GPA up and score around what I did on practice tests for GMAT? What would you recommend I focus on doing to help it more?

Also, I didn't see too much representation for Military candidates on either Harvard or Wharton's respective deferral program. Would this hurt me, as opposed to doing something in the private sector? I'm only asking because I can choose either active duty or reserves, I am fine with either looks best for B school. Thanks
