For whatever it is worth I would be doing a lot of rucking (with 50lbs+) and covering distances of 40 miles or more each week would be the norm. Also running and strength training (particularly push-ups, pull-ups, core work) would be part of my training regimen as well. But, just like I asked you in my previous answer, this program would be based on my current physical conditioning level and the parts I would need to improve. Your mentality and training should be closer to that of a Special Forces level than a regular army. All of the above training suggestions should be done in a full army fatigues and boots.
I hope this helps and good luck to you!
