I used to work on military helicopters. One place you don't want to be is in one in the water, another is under the disk and a third is inside a small box when something big is aiming at it!
Wow, but can you imagine the work that went into servicing the aircraft after that stunt! ( I worked on Anti-Submarine helicopters that routinely spent time in the hover about 40' above the water, we used a lot of WD40!)
Having seen this before this is a standard pickup of Navy Seals in the water and with the rear ramp being lowered into the water is no big deal. I would think the helicopters used for that purpose have a special inspection requirement after the mission is over and that may not be a big deal either. Salt water environment does require additional servicing.
I spent two fun filled years in Vietnam, the second was in the front of a Chinook...a real work horse, that always managed to bring us home safely. With the ramp closed, the aircraft can 'taxi' on the water, and yes the salt water environment requires extra maintenance. To make that video more realistic, they need to turn up the noise ten fold.
