Editing Delta Green (section)

===The Classic Era (1928-1969)===
This is the era where Delta Green is an official organization within the U.S. government, founded after information about the Innsmouth raid makes its way to the Department of Naval Intelligence. Featuring the ONI P4 division going in a Deep One killing-spree world tour, DG fighting against Karotechia in World War 2 and Delta Green fighting in Vietnam, slowly losing it's prestige until it's disbanded after the failed Operation OBSIDIAN. Sadly not too many scenarios are set in this era (perhaps due to the overlap with Call of Cthulhu.) 

The Fall of DELTA GREEN is set in this era, although it's focused on Delta Green operations in Vietnam and Indochina in the 60s.
