Again, serving in the armed forces is not a "freedom"
Negative and positive rights. The govt is not forcing you to do anything, it simply does not want to hire you for this specific task. You are the one trying to force the army to take you in because it makes you sad that your open wound, weak body structure and metal illness and chemical dependency makes you unfit to be a soldier.
You're the ones with your feefees hurt, the Army simply wants to be left alone and hire based on needs and merit.
