Hi, sorry I must being being a bit thick today.
So I download the file from the google drive page 'Training Ready page' (Linked from the top of the main topic)- (right click on the name then download) it downloads as a .miz not a zip?
I copy it into DCSWorld\Mods\aircraft\AV8BNA\Missions\Training?
There are no training missions when selecting Training from the DCS screen.
