A prime time collection of hard-asses. Marines single handedly held off the Japanese (along with the un-sunk portion of the navy) during WW2 while Uncle Sam was busy putting its resources into Europe. They had outdated equipment, and they were under supported. Upon reaching a point where they could get some resources, they pushed the Japanese island by island all the way out of Okinawa.
The Marines also ruined Stormin Normin's plan in the gulf war by kicking the Iraqi's asses so hard that they sent them into a retreat before the main army could get around behind them in the so call hail mary. The Marine attack was only supposed to be a diversion.
Marines pride themselves in marksmanship, and toughness. They have a long tradition, and you will have it yelled at you thoroughly if you join up. You will also do pushups for hours at a time, stand at attention for days at a time, and run for months at a time. So give your heart to Jesus and your ass to the corps. Semper Fi.
