You talked about the obvious desirability of not having sub-to-sub collisions. Within NATO, obviously, we operate very closely. You talked about the non-NATO subs. From your knowledge of submarine ops--the Russians, for example, or the Chinese or anybody else--are their procedures pretty similar to NATO procedures? Do they conform to general safety considerations and communication in terms of avoidance of collision?
Maybe Commander Mulholland would be better for that.
