As a fellow Herk driver (USMC), my experiences tend to be similar to the majority. We have a real unique perspective as well as benefit that our platform relies aircrew that are both officers and enlisted. Due to that, I've built very good relationships with numerous enlisted aircrew over the years. When we have formal events in the squadrons, we typically keep it limited to O's i.e. holiday parties, K-courts, and hail and bails. On the road is a different story. My approach may differ from others, but I never felt like I had to force the enlisted aircrew to come hang out w/ us O's. Once the aircraft was put to bed and we got to billeting, I'd always offer to the enlisted guys that they were welcome to come join us O's in dinner and boozing. Interestingly enough, it comes out to a 50/50 split on whether the guys would join us or not. Sometimes, you would get a group of enlisted that were bros that would join you and have fun. While other times, they just wanted to get away and have fun on their own. Neither is wrong but at least the offer was out there.
