The way I play this whole line was rarely follow the heavys and support the meds, I may follow meds but if map dictates ill go toward middle of map with cover solo to get my position to help the meds flank with cross fire. Never go to desert unless your heavys go desert (no rocks or cover to prevent COD).
Equipment: I use Improved control and gun rammer and extra armour not the extra HP.
You have to have a plan , look at your tanks and were do meds go , say on himmelsdorf my meds decide to go to heavy ally ,( not preferred I think but happens) , I will follow down the side of map to the last pile of dirt , turn around and set up ambush for the rabid red meds and lights zooming around corner looking to get at our rear flank, ive kept 3-4 flanking tanks at bay solo many times while my team goes in a loop around fkn map, always be aware of keeping cupola behind the tallest part of dirt( very important).. On the map with "park" in corner of map, (newish map) and im on the proper spawn side l go straight to the corner and put your right side against the wall and beat up the heavys and take shots on the grille way over to the right. ,you will bounce shots, they cant hit your cupola behind the wall and your gun will swing way to the right such that if a heavy is side scraping the corner , you will tearit a new one and the other heavys will be shot by me, or other heavys with me, with its rapid reload.. its an op tank in my opinion but you have to know what your going to do with your options on the map and what the meds are going to do. I have had 1v1 and won more than a few times with a med or light and as long as you have solid cover you can scrap them of your side, make them pay or die trying to get "easy", TD kill.
