Thank you for trusting your question to JA today. I am a licensed attorney with over a decade of law practice and over 20 years of experience in the legal field. I’m happy to be of assistance.
If you are talking about a federal deployment, that means that they'd have to place you on Title 10 orders to do so. In those instances you are treated as a full time, active duty member.
Refusing a deployment is a violation of the UCMJ and legally you could be court martialed and imprisoned for refusing a deployment. Now, that is not what usually happens. The more common outcome is a punitive discharge through a discharge board, granting an other than honorable discharge which can remove any potential future VA benefits, make you ineligible for any sort of government job (state or federal) and even hinder civilian employment opportunities.
What happens here though would depend entirely on your command and what they are motivated to do. Commanders determine what action is taken, so it will be determined by your chain of command how far they wish to go.
