Ways to incorporate Fhs military background into wedding

My FH is also a Marine, no longer enlisted but of course once a Marine always a Marine, and he will not be wearing his dress blues either, as I do not want him to shave.
We decided that he will be wearing the Marine emblem pin on his boutonniere.

Another thing that we decided to incorporate into our wedding is the idea that a Marine's favorite thing to eat is crayons, so I located a company (owned and operated by a Marine) that makes edible and flavored crayons. We have bought a box for each Marine that is attending our wedding so when one of the Marine groomsman finishes his toast he will ask all Marines to raise their crayons instead of their drinks.

My FH is also military and is still enlisted. He will not be wearing his blues either. About 30 people attending are previous or current military. We are having a celebratory shot during the reception where the DJ will ask them all to stand up, thank them for their and their families service, and cheers them.
