For many the "rucksack" often means our old military pack that we run without the waist belt. Yes, I "grew up" with the same philosophy in my younger enlisted days and then onto ROTC in college where we did competitions with 10K ruck runs; I've done more than my fair share. The concept is supposedly for dumping your pack quickly and I understand that, but even 20+years later, I still think that mentality is simply stupid. Even my son did his Infantry Basic Training this past summer and guess what? New (ish) MOLLE packs and for all their road marches, they could use their pu$$y waist belts. There is a point where "hard" becomes "ignorantly stupid" and this is it.
I've also done my share of distance backpacking; my goal these days is light and mobile. Sure, I have a massive 7000+ cubic inch Kifaru EMR with enough add on pockets and the suspension to support 130-140 pounds...which I've done, but would rather use the pack for cover and engage before running off any significant distance with that kind of weight. Waist belts are critical if you truly want to carry heavy weight over long distances. The "rucksack" method will wear you down faster and I don't care what kind of shape you're in, it's not good for your body...it's stupid.
I've done well over a hundred battle drills reacting to incoming artillery, reacting to an ambush or even hasty contact drills. Yes, we practiced "dropping" your ruck to either engage or break contact...over, and over, and over. If you're planning on just combat drills, sure (I still think it's stupid), but for an INCH or Bug Out type of pack, get a quality pack with a frame and suspension to handle your required pack weight/capacity...make sure it fits you properly! With all the weight on your shoulders, lack of balanced contact points and most likely not well secured, a shoulder-only rucksack is more likely to cause you mechanical injury rather than the often discussed "enemy" threats.
Where the rucksack carry method kills you is the pain and burden on your shoulders, neck and back...I could never imagine doing that every day for a week or so. Proper pack suspension is there for a reason and that includes a properly fitted frame and waist belt that is designed to take more of the weight off your back, shoulders and arms.
