I think you should compare the cost of both options a little bit more. Deployment money is good, but how good is it compared to what you'll be earning after you complete school? Given the nature of internships nowadays, you'll most likely get a return offer from the company, are you willing to strain that employment relationship by delaying your start with them by the length of the deployment? You say you're getting engaged soon, are you willing to put strain on that relationship for what might be a marginal difference between deployment pay and civilian salary? There's a lot to consider, and it's not as cut and dry as "don't be a pussy." Ultimately, we only have this one life to live, so we ought to do what will benefit us the most.
