Makes sense that the Russian troops would use more HE rounds against a guerrilla-type opponent. Now as you said, Spike, the level of preparedness most Russian forces showed in the first Chechnya war makes it hard to rule out that armored troops would have been rushed into battle with "standard" loadout, whatever this is.
By the way, does anyone have any idea of the standard loadout of cat.B/C (do they still use this classification these days?) tanks stationed in central/eastern Russia these years?

On the matter of gun-launched missiles, bear in mind that they could be of some help for taking out point targets like snipers, hidden AT teams, AA guns, MG nests...
I don't know if Russian troops have integrated that in their doctrine, since the only mention of a possible anti-personnel use of these weapons is in the OPFOR's WEG...
