I spend forever trying to find a good thread to append these to … so instead I will make another one! Please forgive me but I will try to keep all 1.5.x change-logs in this thread from now on 
DCS 1.5.7 Update 1 (1.5.7.8899.335)
F-15C: The Georgian War campaign
8 August 2008. The Russo - Georgian war catches four USAF F-15Cs and their crew in Georgian territory. American pilots came to present their jets before a possible purchase of several machines by the small state in South Caucasus.
Although inspired by true events, this fictional campaign puts player in a cockpit of F-15C Eagle. Throughout 16 missions in the space of several days, he will help the Georgian forces face much more numerous and better equipped foe.
