About 150 T-90 of older models were aquired.
You guys always make me jealous. You know things I can't find anywhere. Do you have the statistics still around by any chance?
Sometimes, but not always.
For example, T-90: a quick search would yield you interview 2006 General-Colonel Polonsky. He said, blah-blah, in 2006 31 new T-90 will be purchased up to total 181 tank in russian army. We well know, 2005 were purchased 17 or less T-90, earlier for 5 years - nothing. From other sources i know there were about 150 older t-90 purchased - so the conclusion is either:
1. 17 new T-90 in 2005 were not delivered
2. ~15 older T-90 were lost / upgraded / trialed / sold / whatever. Pretty believable.
But generally, numbers pretty well agree with each other...
