Anyone who has spent time in the armed forces can attest to the fact that it feels like a separate world. Soldiers even have their own language, full of military slang and terms that seem largely foreign to the rest of us. Soldier slang is nothing new; it's been employed as far back as the American Revolution, and some terms have made their way into mainstream vernacular. "Boots on the ground," "in the trenches," and "no man's land" are all soldier phrases that either come from the Marines, Army, Navy, or another military branch.
Given that serving in the military is such a exclusive experience, having a common, coded language inspires camaraderie. Military code words and slang are especially useful when describing military training programs or what it is like to endure unusual military hygiene regulations. Language is a unifying resource for U.S. servicemen and women.
