Battlefront has some more Soviet vehicle action for you again today with their feature article for the BA-20 Armoured Car.
From the article:
Armoured cars are used in large numbers by the Red Army, usually as wheeled tanks. The Mongolians also use them in much the same way as the Red Army. If they are used to do any scouting it is in the un-subtle Red Army method of simply driving until engaged by the enemy, with the sound of the fighting alerting the commander to the presence of an enemy unit.
