Marine Raiders (Original WWII Battalions)

Commando-style light infantry for amphibious raids — Makin Island, Tulagi, Edson's Ridge, New Georgia.

The Story

Carlson's 2nd Raider Battalion adopted "Gung Ho" (from Chinese *gōnghé*, "work together") as its motto after Carlson borrowed it from Chinese Communist guerrillas he'd observed in the 1930s. The slang entered American English from this battalion. MARSOC revived the *name* in 2014 — different unit.
