I honestly have no clue. The only thing I know is from what my dad and my brother say about the food at like Basic Training and stuff- it’s all very basic and it’s designed to fill you up not to particularly accommodate your tastes. And I know that in the field soldiers are issued MREs, and the same goes for them.
I asked my brother about it, he said “It’s pretty much impossible.”
Honestly I have no definite idea so that is something to talk about with your recruitment-person.
