While this really isn't what you want to hear, I have to admit that I echo @nzfxtrader's sentiments. I'd feel like a hollow hypocrite if I didn't say precisely the same.
Your sons' achievements are no small feat. You have every right to turn up the pride to 200% - It is warranted.
However I would suggest that they do whatever reading up on military law necessary lest they make you even more proud one day at great personal cost by simply doing that which is right and not doing that which is ordered - should they ever face such a situation (most likely abroad).
With that damp point out of the way - all the very best to your fine sons. :c)
