Reading the original post, im not quite sure I understand what you're referring to when you mean the Infantry stuff. If you mean, "do we use the same weapons", yes and no. We (the Arty) use C7s, C9s (and to a lesser extent C6s). In addition we use our own Guns... but thats a Given.
Did you mean "do we undergo the same training?". Well, to become even the lower than spit Private untrained on his MOC, you will have passed your SQ (Soldier Qualification) with is, to dumb it down, Section Attacks, Grenades and C9/C6. So.. I dont see any difference between infantry and Arty there. So if the Artillery guys are trained to the same level of the Infantry at That point.. then Why shouldnt the Artillery guys be able to do the same job as the Infantry guys.. when all that is required is that we be able to operate the same weapons.. and provide the same level of defence (or what-not). Granted, on the BIQ the infrantry guy will go into much more depth in certain areas... the Map & compass stuff, and the Basic military stuff will be/is present in all of the combat arms.
As someone mentioned above - Arty guys arent being sent out to do Infantry specific jobs (in the same way an Arty guy wouldnt be asked to clear a minefield), they are being sent out to do GDs. (For the most part).
