Like I said they are different career paths...but they both deal with carrying out tactical missions objectives so that may require a specific type of skillset (generally) that is specialized to their trade. The OP gave some examples that can apply to almost all officer positions...leadership, being able to think quick and act fast in a combat scenario, etc.
Yeah, the reasons you give are some very true differences between the two. I want to know if there are general skillsets that must be learned for officers who have to engage in weapons control/deployment (be it MARS, air combat or amoured) - skillsets that are general 'on paper' but are expanded upon/also specialized for each occupation.
