Because of that the Amphibious Vehicle Test Branch was established. You can check out their website here, but unfortunately a unit history isn't provided. To be quite honest I'm extremely curious and wonder how long they've been in existence. What I do know is that they've had a hand in bringing the improved AAV into existence and they were working hard on the EFV before it went belly up.
The AVTB. One of the unknown units of the Corps.
