Mil Exercise on 3277?

I have just received a report from a Euro reporter of a lot of mil activity on 3277 kHz USB. Stations in this net are using trigraphs (i.e. U0G, etc) and there are frequent messages - in english - and are not in "clear" form. Based on what my reporter has submitted this looks like a naval Composite Warfare (CWC) net. Does anyone have any details on what is happening in the Med on 3277 kHz? I do not have anything in my database from this part of the world. I just checked the frequency at DXTuners and it definitely sounds like a US Navy CWC net. Lots of interference from an adjacent frequency.
