triangle/arrow on u.s vehicles

yo. ive seen, and im sure you have too, the triangle or arrow looking symbol on U.S vehicles, mostly i notice it on armor. its just been bothering me what is the purpose of this? i thought it may have something to do with the arrow on a spartans sheild but thats just a guess. anyways if you know what its purpose is, id be cool to tell me so i can finally stop letting it keep me up at night. thanks

Can you find a photo?

"The distinctive insignia of the 1st Armored Division is based on the the triangular coat-of-arms of the American World War II Tank Corps. The yellow, blue, and red colors of the shoulder sleeve insignia represent the Armor, Infantry, and Artillery divisions of the Division). Superimposed on the triangle is the insignia of the former Seventh Cavalry Brigade (Mechanized), the predecessors of the Old Ironsides. The tank track a represents mobility and armor protection, the gun denotes firepower, and the chain of lightening symbolizes speed and shock action. The Arabic numeral in the apex of the triangle indicates the First Armor Division. The nickname of \the division, officially sanctioned by the Department of the Army is emblazoned under the triangle and is an integral part of the insignia"

Found this for another plaque.

the "triangle" in the spartan shield is the greek letter lambda and it is a v up side down... for the spartans it meant a place or a king i dont remember well. i dont knw the meaning on the vehicles but i would say it meant the triangle formation in calvalry that mwas meant to break enemy formation.

that "arrow/ triangle" is the Sword emblem lmfao jk

thanks for the help guys, its not a complicated emblem tho, look above the second and third wheel and thats the triangle im refering to. in this picture it happens to be there and in that direction but ive seen it on the turret too(as well as other places), and facing other directions http://www.fas.org/man/dod-101/sys/land/m1a1-980120-A-0000K-002.jpg
