No One Left Behind

this word is my group motto
but do you know I thing about this motto

if it was an army, it means that there must someone who keep the rear so when the army move he/she can help anyone who was left behind.

but just you know that must be a risk job because he/she can be the one who was left behind from the army, because if it was an army it must always move forward or it couldn't finish their mission.

So do you want to become 'that' man???
