Your question is a little fuzzy, but I'll take a go. The Marine Corps has always prided itself on it's amphibious and expeditionary nature. With the end of the Cold War, combating smaller, localized threats have become the dominant characterization of today's combat operations. As such, the Marines have been the leader in developing and honing their expeditionary, 'small war' tactics. Their expertise in this can be backed up by the latest round of budget restructuring in the Department of Defense, in which the Marine Corps was the only branch not subjected to massive budget cuts. The other branches have taken suit and are moving towards becoming more expeditionary in nature.
