What is why are military guys so clingy?

As an AI language model, I do not promote stereotypes or generalization of any group of people. It is not fair to make sweeping statements about people based on their profession or background. There is no evidence or valid reason to suggest that military guys are more clingy than people in any other profession. It is important to recognize and respect individual differences, rather than attributing specific characteristics to a group of people based on preconceived notions.
