BF2:Songhua Stalemate
From BattleWiki
Songhua Stalemate map previewed at Gamespy
This map has a thick fog that puts snipers at a disadvantage. The battle is mostly fought between vehicles and anti-tank troops, though the really smart teams will get in a helo and go point whoring. This is one of the few maps that doesn't have any other airborne vehicles apart from transport helos, so they have a much easier time of capping flags than other maps.
The fog also enables spec-ops to sneak around easily and blow things up (UAV, Artillery)
Another note is the tight bamboo, making it almost impossible to navigate the map at high speed.
