Russian language extension?

[Cat1981England]

Hello all.

I'm hoping someone could tell me what the three letter file extension is for Russian language files/or if it even exists? My game comes with German (det), Spanish (est), French (frt), English (int) and Italian (itt) but not Russian and i need it for a server mod.

Thank you in advance.

Never mind. We've since found out that it's .rut

Also it's not an official UT2004 language, but I suppose it can be considered the defacto standard.
