Alrighty, a couple notes. First, I am gonna recommend a different first name only because Luke is a very human name and your character is obviously not. Second, go ahead and move the stuff in the additional kit section to your kit. The books can go right into the backpack and the knife can replace the entrenchment tool (you also listed your grenades twice). Finally, I added a Marksman kit that would fit your boy better then the rifleman kit.

Aside from those tidbits it looks good! You gonna be able to handle being in command of more then 2 dozen troops? If not then Lance Corporal may be a better fit
