It must be true...it is in technicolor!
The Pentagon has released a time-line and color enhanced video shots that establish beyond doubt…..absolutely nothing (LOL). It seems to me more likely that the video was originally in color and then deliberately degraded.
What you apparently see are a number of Iranian special forces (in high visibility life-jackets)
rescuing the crew removing a mine. It is interesting that the patrol boat is alongside the T-with-arrow marking as this is exactly amidships and therefore has the least roll and sway for attaching a Jacob’s rescue ladder. Notice the time stamp (13:18) and the very long shadows (sun should be overhead casting small shadows) notice the white draft gauge markings (not present on the CENTCOM image of the current tanker). Even if the story is true (sic) the Iranians are removing mines not placing them. If they are removing a mine they are doing it in an incredibly stupid, nonchalant and unprofessional manner. Of course this critique has already been per-empted by the ABC;
“The officials described the attempt to remove the unexploded
mine in the way shown in the images as "very high risk"
and not a way that the U.S. Navy would have ever undertaken.
According to those officials they would have removed the mine
remotely with as few personnel around the ship as possible”.
So, the Iranians who supposedly planted the mine were too stupid to know how to safely remove it (LOL).
Firstly, this could be a picture of anything (it has no context) and secondly what is the raised round disk? Could it be an anode? 
Iran or Israel?

 Anode ----Zink or aluminum or some such alloy that is fixed to the hull of a vessel. They are 'eaten' up by electrical currents moving from the vessel to the water. The anode is sacrificed to protect the metal hull of the vessel - without the anode, the hull plating would be dissolved by electrolysis.
