Ah, right. Sure. Since the military no longer fly taildraggers, there's no reason to carry a slip or curve as deep into final approach.
In the curved approach, I find it much easier to estimate, right from the beginning of the descent, how the whole thing is going to go and what slight variations I'm going to need to make to hit my mark. I find that harder to do in an approach with two vectors 90*s appart. Maybe that's why the military do it that way? Also, one curve which is constantly updated is actually easier to fly and is less disruptive/discontinuous than two legs 90*s apart.
Would love to get an hour in an F-15E to see for myself!
