I'm an officer cadet in the artillery officer trade currently attending a civilian university. I need advice on whether I should think about requesting an OT. I know from reading the posts on this board that this is extremly difficult, even more so as it seems the CF is in need of artillery officers. I chose infantry and armoured ahead of artillery on my application form when I first applied, not really expecting to be picked for artillery and I was admittedly naive and ill-informed as to the extent of the technical nature of the job, and yet that is what they chose me for. The problem is that I dropped math after grade 11, and don't have a background in either science or physics. While I was at St. Jean in the summer, most of the artillery officer cadets were in math related subjects, while those in the infantry were more likely to be in the social sciences. My question is how vital is Grade 12 math and calculas? Is it possible to be a competent Arty officer without a background in math? Can anyone give me a few examples of specific applications of math and physics to artillery?
