The Soviet Heavy Artillery Position is a fortification armed with a pair of heavy-duty, long-range 155mm artillery batteries entrenched in heavy duty concrete. This bunker has a range 400 meters longer than that of its smaller, lighter brother, the Soviet Artillery Position, and hurls shells with significantly more explosive impact.
The Soviets should protect this position further by adding several 'minor' fortifications to it as well. For example, a regular 'Artillery Position' is recommended. If possible and if present, a teammate should add a machine gun position close to it, since infantry up close can destroy this emplacement easily.
The heavy artillery position may be used as an excellent second offensive line. If the USSR player have achieved good forefront lines with AA and AT units, relatively close to the enemy buildings, the heavy artillery positions may be deployed behind that, and they will destroy methodically as buildings as they find positioned in their fire range. They are strong and solid, but, in exchange, obviously static.
