Rey, do you need a blow in the bag?

It's simple, Clark was stating that the TK22 will allow you to do all four functions you listed as a,b,c, and d, while on the move and will allow you to combine, as an an example, a, traversing the turret + b, elevating the gun or c, firing the main gun + d, secondary fire/MG.

Of course I could be Galah !
