Bloc
Large map with great sniper locations. Avioid being caught in the middle because you are sitting duck for even the mediocre sniper. To assualt your chosen building, attack from the side entrances.

Back pool area and far garden provide excentlent cover if you are so lucky for a headquaters to spawn there. Use Night Vison when entering the left building, dark places are camper haevans where they lie in wait for anyone carelss enough to rush in for a simple enough backstab.
