I work in UAS plans and policy at HQMC these days and as such we talk to just about everyone in DoD who flies drones. All I can say in open source is that this topic is discussed, a lot. I'd say it's the main UAS thing we talk about at the inter-service level, and quite a bit of attention is focused on how things are going in/around the Black Sea AOR. There's some really neat shit being developed by private industry and within the DoD.
Yup. A very hot topic indeed. I think that's really about all that can be said.
