1^st Marine Division

První jednotky 1.divize USMC začaly přicházet do Vietnamu až v druhé polovině roku 1965. Jednotky USMC operovaly především v I.CTZ a 1.divize USMC zde provedla desítky větších či menších operací, z těch známých jsou to třeba operace Hastings nebo Union I a II.

Pěší pluk USMC si držel klasickou plukovní strukturu se třemi prapory, každý prapor měl čtyři roty. Roty byly označeny písmeny A-M (např. Kilo Company, Lima Company) písmeno J bylo vynechané. K prvnímu praporu patří roty A-D, k druhému E-H, ke třetímu I-M, tak jak je to v tabulce. Celá struktura regimentu USMC je potom na obrázku pod tabulkou.
