True. I read somewhere that one of the Navy boats lost power, and drifted into Iranian waters. Which leads to this question: Why didn't the other boat take the disabled boat under tow?
The only reason I can imagine is - well, two reasons - either they did not have a tow line or they were ordered to stay in place until whatever was wrong was righted.
Either way it looks really bad for the Navy’s preparedness and command level decision making (unless orders came from the US ...)
