I learnt you can save up points to hand out better promotions and awards later. T-72's, BMP's, BRDM's and loads of infantry. You get support units as well, and you can control them but only on an overhead map. You can view every vehicle from the outside but you can only get an interior view from one of the four tanks. You can unload friendly infantry from APC's and tell them to move separately.
Graphics are most reasonable.
When you hit a T-80, sometimes the turret will fly dozens of meters into the air, flipping end over end. Other vehicles eplode into a fireball, some just come to a stop, only to have you finish them off or to leave them stationary and lifeless. After a vehicle is destroyed it usually sends up a column of smoke. This doesn't stop burning as far as I know, and occassionally you hear ammunition explode inside the destroyed wreckage. Firing the guns are really cool, but you have to hear the A-10's chaingun go off to appreciate the true meaning of force.
