ok en la guerra 21
It probably refers to the origin of the term OK during the war in the United States, on which there are two versions. The first says that during the US civil war (1861-1865), when troops returned from a fight, officers were responsible for making a report. When there was no casualties (soldiers killed), they wrote on a chalkboard quot; 0 Killed quot; (zero dead). With the time, this term is developed in OK. Another version says that during the war of independence, had troops of Hessen which Supreme Commander (Ober Kommandant in German), signed the parts of war with the initials OK.
