If you haven't experienced Marine Corps training then you have no place commenting on how it works and you clearly don't understand what truly makes a military efficient.
Allow me to correct your mistakes so you don't confuse or mislead anyone else. Recruits are not beaten senseless, maimed, assaulted, or forced to commit suicide at any point in training in any military branches of the U.S.
Drill Instructors are not permitted to strike recruits for training purposes or any other except cases of self defense which would be extremely rare.
The reason Marines are so effective in combat is not because of their equipment (which is pretty much Army hand me downs like the hueys that have been used since Vietnam) but because of the way they are trained to handle situations of extreme stress and high physical demand with minimal supplies and support. If you simply take some average citizen and teach them to shoot a rifle and use other military equipment until they are expert marksmen then send them into combat they will almost certainly get themselves and/or others killed. They will likely panic when someone starts firing at them rather than react tactically to neutralize the threat. The army has far better equipment and about 4 times the budget yet the Marine Corps is still considered our elite branch. I won't argue that having better weapons than an enemy can make a difference but only if they're in the hands of brave men and women who are not only physically but mentally prepared for war. Bootcamp isn't about getting beat and tortured it's about breaking down your pride and ego and showing you how much you can take and then building you up to withstand it and surpass what you thought your limits were. You learn to stay sharp and focused in stressful situations and practice fast paced problem solving You'll work with whatever you have because you never know what may happen. You learn to trust each other and work as a unit because your lives will depend on it. Marines come out of bootcamp with great respect for their drill instructors no matter how hard they've made life for 3 months because now they are stronger for it. If we were simply beaten and abused we would feel like we were escaping from cruel captors
not like we had accomplished something many don't have the will or mental strength to do. Any football coach can get you in good shape and sharpen your skills but being trained for war takes much more.
I believe you meant well with your comment but the truth is you are too ignorant on the subject and have no understanding of military training or operations to be throwing your opinion around like that. Do your research first next time please.
