What’s the tea on green beret soldiers?

So I’ve known this guy for 5 years but because of medical school and my hectic schedule I couldn’t date him plus, When we first started talking he was a marine and was stationed in Japan. But we always talked and he’s always been there for me. Fast forward 5 years later, he became a Green Beret special op soldier and I’m a doctor so my schedule isn’t as hectic and I’ve decided to give dating another try so I thought okay this man has always been there for me, he’s always been open about liking me I should give him a chance, right? Problem is I’ve always heard negative things about dating soldiers, and how they’re whores lol but because I’m a physician I don’t want my time to be wasted. So like the title says has anyone dated a special op soldier? What was your experience? Tips?
