Ukrainian Pilots Already Training For A-10s - AVweb

Sounds a LOT like DCS and their A-10 module to me…

I find great irony in the fact that, more than 30 years ago, Eagle Dynamics, the publisher, was originally founded by Russians in Moscow. In the meantime, it has relocated to Switzerland and has become quite an international company, with a huge following.

DCS as a platform is well worth a look for anyone interested in military aviation. Their A-10, F/A-18C and AH-64 packages, among others, are second to none and have a steep learning curve (they are so realistic, you can e.g. read the real NATOPS manual for the F/A-18C and find it simulates most of what’s in there quite accurately).
