Exiting Military / Sophomore Resume Review

I have a bit of an unusual background in that while I went straight to college after highschool, I decided to take a break after 5 semesters to spend some time in the Army. To make a long story short, I was an outstanding student in high school however I partied too much early on in college and so the Army was a way for me to get my head on straight and mature a bit. After some time in the Army I'm heading back to school this fall as a junior, by hours anyway. Despite my junior standing I have another three years left due to switching my major from Mechanical Engineering to Finance, which thankfully will give me some extra time for another internship.

I have a few friends who are passing my resume around this fall so I'm trying to polish it up now, before I send it out. My biggest issue is merging my schooling and accomplishments prior to my Army time with my stuff after the Army and making sure that it still flows and make sense. Any and all advice is welcome and appreciated, I have a thick skin.
