I noticed you didn't mention your age. I presume the "1990" part of your name means that you're 19? If so, you probably know how the group responds to being too young. If you're not 19, say it, but if you are then you have some great things going for you.

1) Take advantage of your natural test levels. You'll be amazed how well it can naturally pack on at that age.

2) You're in the military. Combine that regiment with your age and workout ethic, and in a couple of years your friends and family won't even recognize you. The food sucks, but they do keep high protein rations and you usually don't see too many soldiers going catabolic. Find ways to get more rations.

Good luck, and thanks for your service!
