In order to change the curriculum it takes time - at least a year and I know the DS try and insert more "current" material when they can, but if they do it's at the expense of something else. The idea behind the course is to not make anyone a shake-n-bake expert, but to learn a set of tools that can be applied to almost any military problem and be able to solve it logically and then communicate that COA to someone else. It's the same as becoming an expert in war fighting, which can then be used as a platform for OOTW.
Without blowing my own horn, I thought I was a pretty good staff wiener before I started and I quickly realized that there was a lot that I didn't know and it really opened my eyes and made me a better officer. Way better. So yeah, I think the CF gets some good bang for the buck of that course. My 2 cents...
