@shishir: You're an idiot. You talk like you know what the Marine Corps is like.
The US Marines have extensive training in practical and efficient hand to hand combat techniques. They are trained in modern fighting with sticks, knives, and unarmed combat.....aside from their marksmanship training with firearms.
Marine fighting style is very scientific and designed for maximum effectiveness. A rather large chunk of their training is devoted to Martial Arts. They are trained to win. Career Marines have the equivalent of a black belts in their hybrid fighting style. I'd say a Marine would win. Spartans are trained to use swords and spears. Without weapons, they can't do much. Marines know mixes of Muay Thai, Wrestling, BJJ, boxing etc. aside from the fact they have combat training that cannot be revealed to the public/civilians. MARINES WIN. OORAH. Semper Fi
