The lineage and honors certificate is a legal document, which contains certain words and phrases, that have a specific meaning.
it is the official "birth, graduation, wedding, and death certificate" of a unit.
As a U.S. Government generated document it cannot be copyrighted and is in the public domain.
It is also used to keep track of a units awards, and battle honors.
This can confuse the layman in that a unit that served in Europe can have South Seas honors from another unit with which it combined.
