Need help for DGen editing.

[Flanker1985]

Hi Guys. I recently downloaded that France DGen Campaign. But the aircraft they used are not historically accurate. So I have been doing some editing. But I encountered some problem about those files which their name started with ops. For example when I open file "opsBOF1", BOF stands for battle of France. But when you open it, it is full of things like
"oRuAttackSoft 00101:50509 VVS 6Y 3B LW 2F 4F"
Why there are full of "Ru" and "VVS"??? There are no Soviet forces in those campaigns. So I thought better not to touch them until I ask you professional guys first.

Thanks in advance for helping me.
