For the first phase before any of the second objectives have been captured just run around in a Obj.252U/Defender or VK100.01P and make yourself as hard to kill as possible OR Queue up in an SPG and stay safe behind friendly lines and target the people in the cap circle.
After the second phase starts be sure to drown yourself or crash of off a cliff don't J out so that no one gets experience for your death, re spawn in one of these tier 9 tanks & begin costing people more credits.
AE Phase 1
VK 45.02(P) Ausf. B
