'Keep our 15thMEU families in your thoughts and prayers,' the Marines said on Twitter.

'I know all of us in the USMC family are extremely saddened following the announcement of the end of SAR operations,' added General David H. Berger, 38th Commandant of the United States Marine Corps in comments he tweeted following the announcement. 

'This difficult decision was made after all resources were exhausted.'

The marines said they conducted an extensive '40-hour' search. More than 1,000 square nautical miles were covered.

The submarine support ship HOS 'Dominator' had joined the search Friday. 

One sailor and 15 Marines were inside the 26-ton military vehicle when it sank into the Pacific Ocean Thursday.

Berger said during a press conference at Camp Pendleton that all their AAV's will undergo a review.  

'All AAVs across the fleet will be inspected,' said Gen. Berger, USNI News reports. 

'This is to ensure out of an abundance of caution that we take the time, give the time to the recovery and find out what actually happened. [AAV] units can continue to train ashore. We’ll wait until we have a better picture.'

The AAV sank while leaving  Clemente Island for amphibious warship USS Somerset, and is believed to have dropped down in 600ft of water

But it's unclear how long the wait will be because the sheer depth of the AAV's descent into the water complicated matters.

Gen. Osterman added that the AAV 'is really below the depth that a diver could do.

'So we are working and we really owe an incredible gratitude and thanks to our Navy and Coast Guard brethren who’ve helped us in this endeavor. They are actually working with us to provide assets that can basically get down and take a look at the AAV.'

Search and rescue options began immediately after the AAV sank. 

At the time of the accident, the Marines had been training on San Clemente Island and were returning to the amphibious warship USS Somerset. 

'An immediate response was provided by two additional [AAVs] that were with them…. as well as a safety boat,'said Osterman.

The island, which sits about 78 miles from Camp Pendleton, is managed by the Navy and houses a number of training facilities. 

The New York Times reports that two nearby amphibious vehicles witnessed the AAV sink and were able to positively identify the exact location.

 'The adjacent A.A.V.’s watched it go down, and at 26 tons, the assumption is that it went down to the bottom,' said Lt. Osterman.

He estimated that oldest service member aboard was in their mid-30s and the youngest was near 18-years-old.  

'This mishap is under investigation. We will share the results of it once it is complete,' said Gen. Berger. 

There are about 800 AAVs in the Marine's inventory and each weighs 26 tons and can carry up to 21 people.

In 2017, 15 Marines were injured when a AAV they were training in caught fire at Camp Pendleton. 

Marines have utilized the vehicles to move troops from water to land since the 1970s.  

The 15th Marine Expeditionary Unit said that they have notified all the families of the Marines and Sailor involved in the tragic accident
