The Graveyard Shift Addon Collection by DOA - Last revised 2008.
(DOA is also known as David ARMAstrong) 

@TGS is the addons collection used by DOA and the other mission editors at The Graveyard Shift to create and run missions on our Operation Flashpoint servers. 
This last pack was done in 2007-2008. It has not been updated since. We moved on to Armed Assault and then ArmA. Most of us enlisted back in 2001 with the original release of Operation Flashpoint: Cold War Crisis. We made a lot of life long friends from all over the world. We have had many many years of top shelf gaming, way too much time to measure in mere hours, all provided by Bohemia Interactive. We can't ever thank them enough. 

@ECP was also used by our group.

OFPEC Enhanced Configuration Project

The Enhanced Configuration Project (ECP) is an OFP 'modification' that aims to increase the potential of OFP through providing enhanced configuration files and associated scripts that run without any in-mission triggers or code. The ECP provides:

Additional special effects
Improved sound
Realism enhancements

In addition to increasing the enjoyment of the game for individuals, we aim to provide an open-source enhanced configuration for use by all mods.
