When playing on a full server, the fight in and around this Mining Area can get extremely intense. If you find yourself on the valley floor, immediately seek cover among the small buildings or mining equipment.
The hillside to the east is a popular sniping spot for recon players. From this high vantage point, they have a relatively clear view of the map. However, the hillside offers very little cover, making it fairly easy to counter-snipe these opponents.
Or look for opportunities to flank squads camping the high ground by attacking from the north or south and claiming the high ground for your own team. Instead of trying to occupy the center of the map, work the perimeter.
Otherwise, enemy attacks can come from any direction. Still, an organized team can make a solid defensive effort by claiming a fixed position and holding it. Just make sure you have plenty of teammates around to cover all angles.
