@dormor, short and sweet, love it! And what's great is there's a lot of strengths in evidence even in that quick sketch. You're well qualified for any of the programs you named based on the basic stats of GMAT and GPA - and that GPA is super impressive, all the schools like a good student. You also have some incredibly diverse background stories with the military plus the education. You're moving to the 'older' side but it looks like you've done a lot in your life already and the schools will appreciate what you bring to the table. There are many positive elements that we're perceiving here.
That list of schools is also ideal for a goal to go into a tech company (which is what we assume you mean when you say "Internet"
). The one outlier is Tuck, they're not famous for technology though it's an amazing general management education and you could do most anything with a Dartmouth MBA. The others are perfect fits, particularly Duke and UCLA. Stanford is Stanford, we can never tell someone if they have an honest shot at Stanford or not, particularly with just a short one-paragraph introduction, but you look like you have a lot to offer and we'd encourage you to go full steam ahead - you never know!! And you're presenting some essentials that can often open doors. Whether it'll be enough to prompt them to invite you in is another thing but you look like you've got the raw material to work with such that it might happen.
If you have follow-up questions we can help with please lay them on us - you appear to be an interesting candidate and that's always interesting for us to work with.

ETA: Want to specifically mention that undergrad thing - it sounds like you went back to school to do that later in life. No problem with that necessarily; you will just need to explain your work/school history appropriately in the apps. It looks like you started in the military after high school and that is fine. You're clearly a go-getter and that's what counts. A nontraditional background is never a disadvantage, it just needs to be properly explained and positioned in the context of the MBA application.
