In the conquest #3 mission, which ever team can rush the hill next to the capture point gains total control of the map, with clear view of both spawn points. Both the spawn points are placed on lower elevation and on wide open terrain with next to no cover, while the hill crests in the middle of the map have the advantage of higher ground in addition to tree and bush covers.
The team with faster tanks that can reach the hills first is almost guaranteed to win. Most games tend to be over in the opening 2 minutes because of this.
