You are right about the reporting, specially with how important the strait is.
All I've read lately, besides the US government spamming videos with blown up boats like it's COD, is stuff like this from random people. I have no clue how accurate any of this is but if a simple speedboat can be easily tinkered to lay those mines, then they are kinda screwed with stopping Iran from doing it.
Again, no clue how real it is but if true, it feels like destroying hundreds of TELs and Iran still being able to throw those bullshyt drones because they can do it from a truck that takes a couple of days to make them operational for launch
