if you think even for a second its going to be easy you should quit right now.
its very very hard.
marines have the hardest training in the entire armed forces.
i've heard stories of no sleep, gas chambers, one meal a day, 50 mile hikes.
if you think you cant do it, then your not ready for the marines.
marines KNOW they can do it.
it's not only about your body, its about your drive, abition, dedication.
good luck.
