As technology advances, and our guns will be able to orient and fix themselves using GPS and autonomous systems, you'll probably see the gun troop become more important and more independent. If the Royal Regiment does buy a system like LINAPS, and integrates computation of firing data into every individual gun (hence supplanting the Battery CP), then it's quite possible that you'll have troops of artillery finding their own firing positions, loosely controlled and coordinated by Bty HQ. The traditional tasks of Bty recce and survey are going to eventually become a residual / redundant capacity, held by batteries in case the gadgets break or GPS coverage is denied by our enemies somehow...
In short, right now the troop is primarily administrative, but that will change as technology and tactics in the Canadian Artillery evolve.
