Initial staging areas are separated by a wide open field, ideal for artillery and defensive operations. Make use of flanking maneuvers and natural defenses like woods, hills, and farmhouses, as these can be decisive. Another option is a well-coordinated high-speed combined arms attack across the field which could bring victory, but at the risk of a bloody loss. Colloquially also known as "Campingnovka" for the tendency of most players to just sit behind cover on their side of the starting field and snipe each other.
There are plenty of different theories on how to win this map. The trick to doing well here is team work, regardless of the tactics used. While communication is often difficult in Random Battles, having just a few people talking to each other can turn the tide. Artillery has little to stand in its way if appropriately placed, less the depression on the west spawn and the buildings in the east spawn.
One strategy is to send Light tanks to take an obscure route while Medium and Heavy tanks cause a distraction and hold the line. Meanwhile any and all available Artillery should be on standby for when the Light tanks flank the enemy and start marking targets. As for Tank Destroyers, well, they get a whole range of roles. They can snipe, join the medium and heavy tanks in the assault, protect the SPG's... the list is endless. Of course this level of organization is almost impossible to obtain, but if people are familiar with these tactics then hopefully they will move to fill an appropriate role.
Another common tactic is to leave a few TD's or heavies on defense at each spawn and have the rest of the team go up the hill to the north. Artillery can harass the enemy defenders should they stick out too far, but their primary job should be to cover the assault up the hill. Should a light tank break into the enemy camp, artillery should take out the opposing artillery so their teammates can operate without fear of HE raining on their tanks. Generally, the team that controls the hill will win the match, as from this vantage point TD's can hammer the enemy defenders and the team Mediums and/or Heavies get decent speed heading downhill allowing for "faster" than average maneuvers.
