This is the control station for the externally mounted grenade dispensers.
The left panel is for smoke grenades (eight total, four in each bank). Press the red button to launch. The gray rotary dial is for selecting individual pairs of grenades for launch, or launch all four in either bank simultaneously. There's also an option to launch all eight in one go.
The right panel is for shrapnel grenades (four total, with two in each bank). Red button for launch. Gray rotary dial for selecting which one of the four for launch. It appears shrapnel grenades can only be launched singly.
Both panels have numbered indicator lights to inform the operator whether a particular tube is loaded for launch.
