Actually you joining the military has everything to do with how you carry yourself in the real world. You will be representing a branch of the armed forces not to mention a country.
Believe me on this one, anything you do to make the Navy/USA look bad WILL come back to haunt you. Military/Law enforcement etc. in particular care a great deal about what you do, because you can make them look bad. And the last thing you want to do is make your (most likely very patriotic) superior angry with you because you're acting like a jackass.
As for the whole grammar thing. It's not the most important thing in the world. But when used properly does make it easier for people to understand you and help you with whatever it is you need help with. Also having good grammar can be a point of pride. Have pride in the way you respond to things. Also writing poorly will just make people ignore what you are saying, because if you didn't take the time to make it understandable for everyone else "why should they take the time to help you?"
Don't take this too harshly, just some advice.
