All missions take place in various regions of the Caucasus map.
A series of quick missions (Most take 3-10 minutes, though 'Advanced' and 'Expert' missions may take longer), designed to help Strike Eagle pilots practice their systems workflow, refine their key binds and HOTAS controls, axis curves, and employment proficiency with a variety of both air-to-air and air-to-ground weapon systems, Air-to-Air refueling, as well as some more advanced scenario based training, that will test your flying abilities while expanding your skills. These are designed to be quick and hassle-free ways to practice selecting the weapon systems, picking your modes, options, ripple patterns, etc. in order to ingrain good muscle memory and habits so it becomes second nature when flying real missions.
These are all copied and/or adapted for the F15E from my Viper practice & proficiency mission pack: https://www.digitalcombatsimulator.com/en/files/3328191/
