Virtual training?

Do airforces make much use of this?

After all, flight simulators [including the big fancy ones] have been around for ages now.

Alot of the time you see people mention hrs/year, but do any/many airforces log “virtual hours” for training too?

I know you won’t get g-effects, but you should be able to get pretty much everything else now with modern computers. Tactics could be worked on for example, and net-centric warfare for sure.
