Russian last name problem

[Slaists]

A minor thing, but it still looks sloppy. In Russian, last names take two gender forms, female and male. For some reason, CA has assigned female last name forms (ending in '-va' & '-ya') to many male characters in the government and among the agents...

On the same token, I find it highly unlikely XVIII century Russian soldiers would address anyone with "Da, ser" (Yes, sir). "Ser" is used in modern Russian for situations translated from English (if there is a reference to "sir" in the original) not in the native speech or formal army addresses.
