We used to play tag with them a lot. Once we chased a Russian trawler (spy ship) way into their waters until we saw several several surface contacts on radar heading toward us and then they chased us back into US waters. One thing I learned that day, our ship was faster than theirs were by about 10 knots.
Another time we took SEALS to repair an underwater telecommunications line at Fairway Rock. Pretty sure MaBell didn't use SEALs to fix the phone lines. Figured out later it was part of the underwater listening net for subs.
