For those of us that can not tell a Gecko from a Goa (plus I wanted a reference guide for mission building) I have converted a resource I found that explains all of the DCS SAM site equipment.
Hope you find it useful.
This is DCS. They’ll produce a map of Craggy Island before anything useful like the Korean peninsular or the Gulf of Tonkin.
I would imagine the promo video will be the usual mix of stirring music, 3 second cut scenes of grey aeroplanes and Mrs. Doyle carrying a tea service between kersplosions.
