Personally, I like this one better though. And seeing it's Army it may be more fitting..
[R]ecognizing that I volunteered as a Ranger, fully knowing the hazards of my chosen profession, I will always endeavor to uphold the prestige, honor, and high "esprit de corps" of my Ranger Regiment.
[A]cknowledging the fact that a Ranger is a more elite soldier who arrives at the cutting edge of battle by land, sea, or air, I accept the fact that as a Ranger my country expects me to move further, faster and fight harder than any other soldier.
[N]ever shall I fail my commrades.I will always keep myself mentally alert, physically strong and morally straight and I will shoulder more than my share of the task whatever it may be. One Hundred-percent and then some.
[G]allantly will I show the world that I'm a specially selected and well trained soldier. My courtesy to superior officers, neatness of dress and care of equipment shall set the example for others to follow.
[E]nergetically will I meet the enemies of my country. I shall defeat them on the field of battle for I am better trained and will fight with all my might. Surrender is not a Ranger word. I will never leave a fallen comrade to fall into the hands of the enemy and under no circumstances will I ever embarrass my country.
[R]eadily will I display the intestinal fortitude required to fight onto the Ranger objective and complete the mission, though I be the lone survivor.
RANGERS LEAD THE WAY!

Blessed be the Lord my strength, which teacheth my hands to War and my fingers to fight.
