What Does This Phrase Mean?

On Friday our company sent out an email congratulating people on their various anniversaries within the company, mine happened to be one of them. Our VP then sent me an email saying ''Cagey Veteran!!! Congrats" except I'm not sure what that means? I thought cagey was generally used to describe a lawyer, or someone to be 'cautious' of? Is this suppose to be a compliment or something I should weary of? Any insight would be appreciated, thank you!
