it has BTR 80 turret not BRDM-2.would be really nice to get it

Very unlikely, since the Vodnik was never formally adopted by any army to the best of my knowledge, and adapting the BTR-80 turret to the Vodnik's texture would be too much work for a doubtful outcome.

vodnik in service of Russian MVD(Ministry of Internal Affairs) and 50 of them in service of Uruguay army.But i don,t understand why is that important when there is already game variants of vodnik,s and also other vehicles that in service in extremely low quantity aswell?

1. The Vodnik, as it is in now, was in Arma 2 in two variants (BPPU and 2xPK). We added the GMG version because it was easy to do
2. Adapting the turret of the BTR-80 to fit on the Vodnik would require retexturing, which takes time
3. Time is better spent on other vehicles that are in wide use.

Therefore it is highly unlikely that this is going to happen.
