The Marines have used AAVs since the 1970s to transport troops from ships to the beach as part of an amphibious landing.
Attempts to build a vehicle to replace the AAV during the 2000s were canceled due to cost. The Marines are in the process of testing two versions of a wheeled the amphibious troop carrier that is faster in the water and more maneuverable on land than the tracked AAV.
At the moment, the Marines aren’t expected to retire last AAV until 2030.
