Why did many soldiers chalk UUUU on their helmet covers during the Vietnam War? UUUU is shorthand for “the unwilling, led by the unqualified, doing the unnecessary for the ungrateful”.
The Vietnam War occurred in Vietnam, Laos, and Cambodia from 1955 to 1975. UUUU was the most common helmet logo or slogan that soldiers started to write in the late 1960’s as a way to revolt. UUUU Vietnam was part of the antiwar movement within the troops.
Another anti-authority tactic was unofficial avoidance of combat by units in the field – this came to be called “search and avoid,” or “search and evade.” Patrols sent out into the field would deliberately elude potential clashes with the NLF.
Besides UUUU, there were other political slogans painted on helmets and helmet liners during Vietnam war, including “Kill a non-com for Christ.” This slogan was related to fragging: instead of deserting, soldiers were urged to kill the commanding officer with the fragmentation grenade (any evidence was destroyed in the act).
