One objection is that a submarine should not use a consumer game controller. The counterargument cites Challenger 2 controls, where low cost and users' existing familiarity are advantages. That comparison is challenged because a turret needs only elevation and traverse. The exchange separates the choice of interface from the movements and functions it must control.

Consumer controllers and different vehicle-control demands
Game controllers offer low cost and familiar controls, but a tank turret and a submarine impose different control demands.
