Why are the US Marines so effective?

Answer 1

There are four reasons that can attributed to their success.

First, the corps is all volunteer and therefore, no one is there that does not want to be.

Second, the training is rigorous and extreme. Within this training comes the marine fighting ethos that marines live and die by. The outstanding history of the Marine Corps is instilled in each marine during this training.

Thirdly, the discipline of each Marine is the highest level of discipline of any fighting force (somewhat biased here seeing that I was a Marine). This discipline is the unseen ingredient in many battles that produces a victory for the marines in that battle.

Marines never, never, let down the man fighting beside them. Each and every Marine will give his life to save the Marine fighting next to him.

There is another aspect of Marine fighting that was true in the 60s during the Vietnam War, but may not be so unique today and that is that the Marines were successful because they went straight at the enemy and did not stop till he was defeated. The strategy that the Marines taught the smallest fighting unit-the squad- was always the same---take the battle to the enemy immediately and without hesitation and do not stop until you have defeated him.

because we are Americas pit-bull. we are teased, beaten, starved, mis-treated, and kept in small dirty, disgusting quarters. every now and then we get cut loose and take our frustrations out on everyone around us. YUT!

Answer 2

Because of their discipline and strength

But remember that the U.S. marines are the best as a general branch but there are many elite groups like the seals, Delta, Green Berets, Rangers, and Force Recon which are all better than the average Marine.
