CFE will help you maintain an excellent level of fitness in all aspects. Walking around in full kit, or standard 12 mile in under 3 hours road marches should be realitively easy and pain free (provided you have conditioned and calloused feet). Even longer road marches at an easy pace would be good. CFE will also provide you with an excellent base for more specific training, like for a ruck based selection. I have been following CFE for over a year, mainly to prepare for races, but I also find myself among the top physical performers in my platoon.
I was in Afghan for a 7 month tour used CF prior and CFE during the tour and didn't struggle on the BG Ops and that was carrying 30-40kg and weapon systems when patrolling (64kg BW). Trained in between Ops in Kandahar at the Canadians Gym and there were dozens of guys n gals using CF/CFE!
IMHO I believe CF/CFE is hands down the best system for Military Personal, as the strength training gives you the ability to carry weight without the onset of muscular fatigue that a pure CV training regime allows. I found I was as fast over the ground but didn't find myself "breaking" down under the weight as much. Back, shoulders, hip flexors, glutes, and abs all work hard with a pack on but CF/CFE prepares you easily for this stress. Also, the heaves/ring dips also came in useful for scaling compound walls/vehicle mounting dismounting etc.
Finally having suffered thru some killer WoD's I felt uber confident in my fitness prior to "going on the ground" which is a great feeling.
Now almost a year later I am proud to report the results, we went from me checking onboard and taking over the course seeing 4 months of 34% attrition due to running related injury by week 3 to.. wait for it.. 0.. we now lose an average of 1 out of every three classes (made up of 25, so one of 75 pax) due to "running related injuries" which really comes down to they did not take proper care of themselves. Upon investigation, each instance has been a lack of MFR, compounding injuries, no use of massage therapy, poor diet, poor tech.. and even at that we are only loosing 1 out of 75. These are people coming into the SPECWAR community for the first time, some with limited experience to running and the 10 physical skills as CF'rs we cherish. As far as their scores.. well they definitely speak for themselves.. now many articles have already been published by military orgs showing how much better the function fitness works then the traditional training so I will leave out those stats unless you're interested.. however we have had massive changes in body fat percentages, muscle gain, virtually 0 injury, invaluable knowledge imparted and new CFE and NSW athletes forged with significant accomplishments across the 10 physical skills. Congrats and thanks from all of us for having built this program.
