The Artificial Reef Program used four types of obsolete Army armored vehicles as artificial reef materials off the New Jersey coast. These were cleaned at local military bases, loaded onto barges for transport, and pushed off at their final destination. Once the Army had disposed of its excess inventory, the program ceased, around 1999. The Artificial Reef Program has sunk almost 400 tanks altogether, far too many to list them here in this website.

"DIR" or "Doing It Right" is a system of diving developed by cave divers which involves extremely rigid gear configurations and methodologies. To its adherents, DIR takes on an almost religious significance. For the true follower of DIR, no deviation may be tolerated, because DIR is perfection.
DIR is designed for cave diving. The usual object of cave diving is to go in and come back out alive. In line with this goal of accomplishing essentially nothing, DIR espouses an absolutely minimal equipment kit: "When in doubt, leave it home." DIR also espouses teamwork, mutual interdependence, and close lock-step buddy diving, things that are pretty much unavoidable in the confines of a cave anyway.
