[Galain_Ironhide]

If used improperly, yes HA units are next to worthless.

Not real familiar with the Russian HA units, however take a look at this in-depth HA guide made by Doug-Thompson -

Hunters All Their Lives: A Missile Cavalry Guide

It outlines everything from unit details through to tactics for every faction. Quite a long read but very useful in learning the basics with your HA.
