If you are talking about someone straight off of civi-street, Michael is indeed correct. If, however you mean an exchange of personnel (I wasn't 100% sure what "participants" you were referring to), there actually is...or at least our version of it. In anticipation of fewer platforms being available for Force Generation with HAL class MLRs, OP REGULUS was stood up. It's purpose was two-fold: training experience and learning how things are done in our allied Navies. The idea works for some trades where there is a lot of common ground; navigational, all-ship evolutions, some operator trades but for some the benefits were just not there so these trades generally are no longer part of it. I know of two stokers, one who served in the RAN and the other the Norwegian Navy and as exciting as it was at the time, trade related learning due to different systems and practises as well as both Navies have ISSC in place meant training value toward RCN quals was more or less non existent. As far as I know, it is still running albeit scaled down. I think there are still a few MARS officers doing this regularly if one of them wants to chime in(???).
